Thesis (Ph.D.)--State University of New York at Stony Brook, 1995.

An on-line magneto-optic trap was designed to capture and cool radioactive alkali isotopes, produced in a heavy-ion fusion reaction at the Stony Brook LINAC. With this technique radioactive atoms can be stored in a small volume of a few $\rm mm\sp3$ at temperatures below 1 mK far away from any disturbing host. This is an ideal environment for Doppler-free spectroscopy and observation of nuclear decay. In a first experiment, about 80 $\rm \sp{79}Rb$ atoms (half-life 23 min) were observed inside the trap. An improved apparatus has been installed, and a program to trap francium, a heavy alkali atom (Z = 87) without stable isotopes, has succeeded recently. The long-term motivation for spectroscopy in Fr is the observation of atomic parity nonconservation in this system. The prospects of such an experiment are examined, and its potential contributions to the measurement of electron-quark coupling constants and extensions of the Standard Model are estimated.Subjects--Topical Terms:
