7~2D TRANSFER CROSS SECTIONS IN RUBIDUM IN COLLISIONS WITH CO AND He

本文用荧光法测量Rb(7~2D)原子与CO,He碰撞能量转移截面。结果表明:Rb(7~2D)—He能量转移截面为σ_(fs)=(3.5±0.1)×1O^(-14)cm^2,σ_(tr)=(4.4±0.3)×10^(-14)cm^2。Rb(7~2D)—CO能量转移截面为σ_(fs)=(0.10±0.06)×10^(-14)cm^2,σ_(tr)=(0.00±0.60)×10^(-14)cm^2。

Cross sections for 7 2D in Rb, induced by collisions with CO and He, have been measured using methods of fluorescence. The results show that transfer cross sections for Rb(7 2D)-He are σfs=(3.5±0.1) ×10-l4cm, σfr=(4.4±0.3) ×10-14 cm2,transfer cross sections for Rb(72D)-CO are σfs = (0.10±0.06)×-14 cm2,σtr=(0.00±0.60)×10-14cm2,
