Abstract

Applying diode-laser resonant fluorescence method, the cross sections for the excitation energy transfer of the collisional process K*(42 P 1/2)+Cs(62 S 1/2)↔K*(42 P 3/2)+Cs(62 S 1/2) have been measured. The values we have obtained are σ(1/2→3/2)=77 Å2 and σ(3/2→1/2)=48 Å2. These results complete the sequence of data for the fine-structure mixing of the first-resonance states of alkali atoms colliding with the ground-state caesium atoms.
