6 D TRANSFER CROSS SECTION IN RUBIDIUM INDUCED IN COLLISIONS WITH GROUND STATE Rb ATOMS AND H2 MOLECULES

本文用荧光法测量Rb(6~2D)原子与基态Rb原子,H_2分子碰撞转移截面。结果表明:Rb(6~2D)-Rb(5~2s)转移截面为σ_0=67×10^(-14)cm^2,σ_0=4.3×10^(-14)cm^2,Rb(6~2D)—H_2转移截面为σ_(fs)=0.44×10^(-14)cm^2,σ_0=0.01×10^(-14)cm^2。

Cross sections for 62 D 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 σ_(fs) = 67×10^-14cm2, σ_(tr) = 4.3 ×10^(-11)cm2 and transfer cross section for Rb(6~2D)-H2 are σ__(fs) ~* = 0.44×10^(-14)cm^2, σ_(tr)~* = 0.01×10^(-14)cm2.
