Rubidium 5 2 P fine-structure transitions induced by collisions with potassium and caesium atoms [link]Website  abstract   bibtex   
A diode-laser fluorescence experiment was performed in order to study finestructure transitions between 5(2)P states of rubidium atoms colliding with ground-state potassium or caesium atoms. The Rb(5(2)P3/2) 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) --> Rb(2P1/2) induced by collisions with K and Cs (T = 573 K) are sigma = 54 angstrom 2 +/- 30% and sigma = 15 angstrom 2 +/- 30%, respectively. Assuming detailed balancing, the cross sections for the reverse process Rb(2P1/2) --> Rb(2P3/2) are sigma = 60 angstrom 2 +/- 30%, and sigma = 16.5 angstrom 2 +/- 30% for K and Cs, respectively.
