Hyperfine constants in the 52P3/2state of85Rb

Abstract
The results of a level-crossing experiment are reported. The hyperfine constants of the 5 2P3/2 state of 85Rb are a=24.99(1) and b=25.88(3). These values are compared with those from a previous optical double resonance experiment. When radiative shifts are carefully taken into account in the ODR measurements, very good agreement is found.
