Investigations of the ground-state hyperfine atomic structure and beta decay measurement prospects of sodium-21 with improved laser trapping techniques. - 128 p.

Thesis (Ph.D.)--University of California, Berkeley, 1999.

This thesis describes an experiment in which a neutral atom laser trap loaded with radioactive <super>21</super>Na was improved and then used for measurements. The sodium isotope (half-life = 22 sec.) is produced on-line at the 88&inches; cyclotron at Lawrence Berkeley National Laboratory. We developed an effective magnesium oxide target system which is crucial to deliver a substantive beam of <super>21</super>Na to the experiment. Efficient manipulation of the <super> 21</super>Na beam with lasers allowed 30,000 atoms to be contained in a magneto-optical trap. Using the cold trapped atoms, we measured to high precision the hyperfine splitting of the atomic ground state of <super>21</super>Na. We measured the 3<italic>S</italic>1/2(<italic>F</italic> = 1, <italic>m</italic> = 0) − 3<italic>S</italic>1/2(<italic>F</italic> = 2, <italic> m</italic> = 0) atomic level splitting of <super>21</super>Na to be 1,906,471,870 ± 200 Hz. Additionally, we achieved initial detection of beta decay from the trap and evaluated the prospects of precision beta decay correlation studies with trapped atoms.
