Sažetak
A diode-laser fluorescence experiment was performed in order to study fine-structure transitions between 5 2P states of rubidium atoms colliding with ground-state potassium or caesium atoms. The Rb(5 2P3/2) state was optically excited and the intensity ratio of sensitized to direct fluorescence was measured. The obtained cross sections for the excitation energy transfer Rb(2P3/2) to Rb(2P1/2) induced by collisions with K and Cs (T=573 K) are sigma=54 A2(+or-30%) and sigma=15 A2(+or-30%), respectively. Assuming detailed balancing, the cross sections for the reverse process Rb(2P1/2) to Rb(2P3/2) are sigma =60 A2(+or-30%), and sigma=16.5 A2(+or-30%) for K and Cs, respectively.
