A newly developed technique for trapping rare types of radioactive isotopes could breathe new life into venerable accelerators such as LBL's 88-inch Cyclotron.
The technique, developed by researchers in LBL's Nuclear Science Division, enables these radioactive isotopes to be captured and collected 100 times more efficiently than ever before. The technique also permits testing of known phenomena with unprecedented precision.
NSD physicist Stuart Freedman led the team that became the first to capture radioactive isotopes in a laser trap. The key to this success was the use of laser light in combination with a magnetic field to cool down the atoms and slow their motion so that they could be actively loaded into the trap. A competing approach has been to try to snag radioactive atoms at random in an area of containment.
"Our technique is somewhat like pushing ping-pong balls with a bulldozer," says Freedman. "It has to be done very gently."
Freedman and his group worked with beams of sodium-21, a radioactive isotope with a half-life of 22.5 seconds, which they produced at the 88-inch Cyclotron.
"We selected sodium-21 because the laser technology and basic techniques for manipulating stable sodium are well established," Freedman says. "Furthermore, the beta decay of sodium-21 can be used to study the weak interaction and I have always been interested in doing high energy physics at low energies."
In their experiments to date, Freedman and his colleagues used a beam of high energy protons (25 MeV) to irradiate a heated atomic oven loaded with file shavings of magnesium. From this reaction emerges a beam of sodium-21 atoms. The sodium-21 beam is focused and sent down the length of a beamline through a decreasing magnetic field. At the same time, a beam of laser light is sent through the line in the opposite direction. The light is tuned so that its frequency is just below the excitation frequency of the sodium-21 atoms. This enables the laser beam's photons to act as a brake on the atoms. The decreasing magnetic field keeps the frequencies of the decelerating atoms and the laser photons in resonance.
"Each collision between a photon and an atom slows the velocity of the atom by about three centimeters per second," Freedman says. Atoms in the beamline start out at a speed of about 1,000 meters per second, which is comparable to the speed of a jet plane.
The slowed atoms are directed into a "magneto-optical" trap, a sphere inside a quadrupole magnetic field through which shoot six circularly polarized laser beams. Atoms are captured at the point in the center of the trap where the six beams meet. With this technique, Freedman and his group were able to capture 20 percent of the atoms that went through the trap. The old record for trapping atoms was less than one percent.
Slowing the motion of the atoms also cools them. By the time the sodium-21 atoms were trapped, their effective temperature had been lowered by several orders of magnitude to a few milli-kelvin. This not only helps boost trapping efficiency, it also makes possible the accumulation of the high atomic densities necessary for a number of important physics experiments.
"For high densities, the motion of ultracold atoms is affected by the force from re-radiated photons and there is evidence of interesting collective phenomena," says Freedman. "This is leading to a new picture of the behavior of atoms in intense laser fields. It will also help us probe the long-range components of the interatomic force."
Perhaps the most tantalizing of applications to be realized from this new trapping technique, Freedman says, is the possibility of using it to study the weak interaction.
"By comparing the lifetime of sodium-21 with a precise measurement of the beta-decay asymmetry," Freedman says, "we should be able to learn why parity is violated in the weak interaction, or why only the left-handed component is involved. A decisive experiment could point to the existence of a new family of heavy intermediate vector bosons and a revolutionary discovery."
In addition to their work with sodium-21, Freedman and his group have also begun designing an experiment to produce and trap the first workable quantities of francium, a radioactive element with numerous isotopes.
Members of Freedman's research group at LBL include Christopher Bowers, Brian Fujikawa, Zhengtian Lu, Justin Mortara, Song-Quan Shang, and Eric Wasserman. Freedman has also been working with Kevin Coulter and Linda Young from Argonne National Laboratory.

George C. Pimentel Hall "is a fitting recognition of George's achievements," says Alexis T. Bell, dean of the College of Chemistry at UC Berkeley. "George taught and inspired thousands of chemistry students there."
Among his research accomplishments, Pimentel pioneered new spectroscopic techniques "now practiced in nearly every chemistry department worldwide," according to former dean and LBL researcher C. Bradley Moore, who was a student and colleague of Pimentel's. Pimentel also discovered the chemical laser and built equipment that identified the surface components and atmosphere of Mars.
But it was his dedication to teaching as well as research that "set the ultimate standard for a teacher/scholar," Moore says. "Pimentel put his heart and soul into teaching along with his tremendous talent. His last freshman class in PSL did not even realize that he was losing a very painful battle with cancer." He died in 1989.
During his distinguished career, Pimentel also served as deputy director of the National Science Foundation, president of the American Chemical Society and chairman of the UC Berkeley Department of Chemistry. Among his honors and awards were the Wolf Prize, the Welch Award, the National Medal of Science, the Priestley Medal and election to the National Academy of Sciences.
Seaborg co-discovered ten transuranium elements at LBL, including plutonium. He is the winner of the 1951 Nobel Prize in Chemistry with Edwin McMillan for their work in this field, and was recently honored with the naming of element 106 after him. "The Search for Heavy Elements" tells the story of 50 years of discovery at LBL, highlighting the work of Seaborg and Nuclear Science Division colleague Albert Ghiorso.
All Lab employees and guests are invited to attend the lectures. For more information, contact the Public Information Department at X4015.

Called DOE-2.1E, the new program can be used to calculate the hourly energy use and energy cost of a commercial or residential building.
Like its predecessors, DOE-2.1E was developed for the U.S. Department of Energy. It is a public-domain program that can be used on IBM-compatible personal computers, as well as DEC mainframes and Sun workstations.
Previous features of DOE-2 have been incorporated into DOE-2.1E including daylighting simulation, automatic sizing of HVAC systems, heat recovery, thermal energy storage, and cogeneration
Among the many new capabilities are ice storage and evaporative-cooling models, an enhanced energy cost calculation to simulate very complex rate structures, and a link to the WINDOW-4 computer program that simulates custom glazings.
The LBL researchers who developed DOE-2.1E include team leader Fred Winklemann, Bruce Birdsall, Fred Buhl, Kathy Ellington, and Ender Erdem. Collaborating with them were Jeff Hirsch and Steve Gates of Hirsch and Associates.
For information on obtaining DOE-2.1E, contact Kathy Ellington at MS: 90-3147.
Two LBL researchers have received 1994 Humboldt Research Awards, sponsored by the Max Planck Institute for High Energy Physics in Munich, Germany. John Harris, a member of the Nuclear Science Division's Relativistic Nuclear Collisions group, received a Humboldt Research Award for Senior U.S. Scientists, which is given in recognition of past accomplishments in research and teaching. The award entitles the recipient to stay up to 12 months at a research institute of choice in Germany. Harris is currently spokesman of the STAR experiment, to be carried out at the Relativistic Heavy Collider (RHIC) now under construction at Brookhaven National Lab. He will spend this summer in Germany working with Professors R. Stock and H. Stroebele at the University of Frankfurt and Professor R. Bock at the GSI-Darmstadt. He will concentrate on further integration of European participation in the STAR experiment and will also work on some aspects of the NA49 experiment at CERN.
The second LBL recipient was Peter Jacobs, a Divisional Fellow in NSD's Relativistic Nuclear Collisions group. He received a Humboldt Research Fellowship Award, which entitles him to spend six months at a research institute in Germany. He plans to spend five months in Germany this year, split between Munich and CERN in Geneva, continuing collaboration on the NA49 heavy-ion experiment at the CERN SPS. Culminating about three years of preparation, NA49 will take its first data this November when lead beams at 160 GeV/nucleon become available at the CERN SPS. Jacobs plans to spend his sixth month in Germany in 1995.
LBL Director Charles V. Shank has authored an article appearing in the July 1994 issue of Physics Today entitled "Recharging the Energy Laboratories." The overview article discusses the rich and productive history of the laboratories, as well as the current call for the labs to forge new relationships with industry to help the nation maintain global economic competitiveness.
