Sažetak
The cross section for the fine-structure excitation transfer Cs(6P1/2) -> Cs(6P3/2), induced by collisions with the ground state potassium atoms, has been measured by resonant Doppler-free two-photon spectroscopy. The population densities of caesium 6PJ (J = 1/2, 3/2) levels were probed by thermionic detection of the collisionally ionized caesium atoms from the Cs(6PJ) -> Cs(10S1/2) excitation channel. The cross section for the transfer process at the temperature T = 503 K has been found to be sigma(1/2 -> 3/2) = 45*10(-16) cm(2) +- 20%. The result is compared with previously published experimental cross sections for fine-structure transfer in resonance states of other alkali elements perturbed by potassium and a theoretical value of the Li(2PJ) - K system calculated in a simple approach.
