Abstract

In order to perform laser spectroscopy of radioactive atoms, we have designed and tested a system that produces, transports, and injects them into a magneto-optic trap in a glass cell.1

Magneto-Optic Traps are Set for Radioactive Atoms

Ray L. Ladbury

For years atomic and nuclear physicists have dreamed of doing experiments with dense, trapped gases of cold, neutral, radioactive atoms. With such samples they could perform precision spectroscopy of radioactive atoms, search for electric dipole moments (indicative of time-reversalsymmetry violation), study parity violation and electroweak effects in atomic transitions and β decay, and more. As reported in a recent issue of Physical Review Letters, such experiments took a step (or perhaps three) closer to reality when groups at the Lawrence Berkeley Laboratory, the State University of New York at Stony Brook and the University of Colorado demonstrated the feasibility of quickly and efficiently transporting and capturing large numbers of atoms from a vapor or an atomic beam.

Magneto-optic trapping of radioactive Rb79

G. Gwinner, J. A. Behr, Sydney B. Cahn +4 more

Radioactive $^{79}\mathrm{Rb}$ atoms have been produced in a nuclear reaction and were captured into a magneto-optic trap in a cell. A fluorescence signal was obtained from 80 $^{79}\mathrm{Rb}$ atoms in the trap. The efficiency of the process is estimated as 1\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$ atom in the trap for every atom/sec produced. This efficiency is sufficient to develop further experiments to measure atomic properties of Fr with the eventual goal of observing parity nonconservation effects in neutral atoms of different radioactive isotopes of Fr.

Laser trapping of trace amounts of radioactive atoms

Small samples of radioactive atoms can now be concentrated with magneto- optic laser traps into a very small space and cooled to microdegree temperatures. The first application of these new techniques to atoms with radioactive nuclei offers new possibilities for nuclear physics measurements. The general applicability of these techniques of minute quantities of other materials is discussed.

Efficient Capture in a vapor cell magneto-optical trap

Michelle S. Stephens, Royal Rhodes, Carl Wieman

Laser cooling and trapping of rare, radioactive isotopes has the potential for greatly enhancing experiments in high resolution spectroscopy of exotic species, electron electric-dipole moment searches, β-decay asymmetry, and parity nonconservation. The ability to hold atoms for several seconds at high densities (1011 cm-3) and away from the perturbing effects of the cell walls makes laser cooling and trapping attractive for use in the experiments mentioned above. Because many isotopes of interest for these experiments are difficult to produce, the ability to quickly and efficiently collect these atoms from a dilute vapor is crucial. We have demonstrated a 6% collection efficiency in a special wall-coated cell. We have developed a model that predicts the capture efficiency as a function of trap properties and have developed techniques for measuring the pertinent characteristics.
