Energy transfer in Rb(52DJ,7S)+Rb(5S) collisions

Abstract

Abstract:

Rb vapor was irradiated in a glass fluorescence cell with pulses of radiation from a YAG –laser-pumped OPO laser ,populating 5DJ (or 7S ) state by two-photon absorption .Energy transfer in Rb(5DJ,7S)+ Rb(5S) collision is studied using methods of atomic fluorescence .The resulting fluorescence included a direct component emitted in the optically excited decay and a sensitized component arsing from the collisional populated state. At the different densities of the components , fit a three-state rate equation model to obtain the cross section for Rb（5D5/2）→Rb（5D3/2）transfer: =（3.7±0.9）×10-14cm2 .The cross section for excitation transfer out of the 5DJ doublet are (3.1±1.2) ×10-14cm2.(for J=5/2)and (2.0±0.6) ×10-14cm2.(for J=3/2),respectively .The energy transfer cross section for the Rb(5D)→Rb(7S) is small〔(1.6±0.4)×10-16cm2〕.The 5DJ state is quenched mainly in the reverse energy pooling processes〔i.e. Rb(5DJ)+Rb(5S)→Rb(5P)+Rb(5P)〕.
