Ⅰ. INTRODUCTION The collisions between intermediate -state alkali atoms, which lie above the resonance levels but are not classified as true Rydberg states, and ground-state alkali atoms or molecules, are a complex interaction process. Up to now, rigorous theoretical calculation, physical mechanism and theoretical modal for the process are still absent.

Cross sections for 62D in Rb, induced by collisions with ground state Rb atoms and H2 molecules, have been measured using fluorescence methods. The results show that transfer cross sections for Rb(62D)-Rb(52S) are σfs = 67×10-14cm2, σtr = 4.3 ×10-14cm2 and transfer cross section for Rb(62D)-H2 are σfs*=0.44×10-14cm2,σtr*=0.01×10-14cm2.
