摘 要: | The processes of excitation transfer from the 82S1/2 state to the 62D state of rubidium in Rb(82S1/2)-Rb(52S1/2) and Rb(82S1/2)-H2 collisions have been studied experimentally. During irradiating the Rb vapor, mixed with H2, by two light beams for selective stepwise excitation, the Rb 82S1/2→52P3/2 direct fluorescence and the Rb 62D3/2→52P1/2 sensitized fluorescence have been measured as a function of H2 gas pressure. The measurements yielded the cross-sections σ(82S1/2→62D) and σ*(82S1/2→62D) of Rb 82S1/2→62D excitation tranfer induced by collisions with 52S1/2 atom and H2 molecules respectively. The results are discussed in detail.
