Transfer of Nutating Spin Polarizations between Rb and Cs Atoms

抄録

The transfer of nutating spin polarizations between ⁸⁵Rb and¹³³Cs atoms is observed for the first time. Maximum transfer occurswhen the nutation frequencies are made equal in the rotatingframes. The nutating spin polarization of ⁸⁵Rb atoms is generatedby the periodic excitation of the pumping light and the spinpolarization transferred to ¹³³Cs is observed through the Faradayrotation of a probe beam. The observed time evolutions of the spinpolarizations are found to be in good agreement with the results oftheoretical calculations based on the Bloch type equation of motionincluding the effects of optical pumping and spin exchange collisions.
