RESEARCH INVESTIGATION DIRECTED TOWARD EXTENDING THE USEFUL RANGE OF THE ELECTROMAGNETIC SPECTRUM.

Abstract

The nuclear spin and magnetic moment of 55 hour Cd-115 have been determined by optical double resonance. Positive identification of the iso tope was obtained by the observation of the decay of the resonances. The atomic g factor for the (5s5p)-3P(1) state of Cd has been determined to 10 ppm with a K band optical double resonance spectrometer. Metastable autoionizing states have been discovered in potassium and rubidium and it has been shown that these can be quenched with an electric field (Stark quenching). The hyperfine structure of the (4s4p)-3P(1) state of Zn-67 has been redetermined. Level crossings have been detected in the (3d)-5-4p and (3d)-4 4s4p configurations of chromium; the lifetimes of these states were determined from the widths of the crossing resonances. (Author)
