Fine structure excitation transfer between the lithium D-lines by collisions with cesium atoms

Applying resonant Doppler-free 2-photon laser spectroscopy with thermionic diode detection, the cross sections for the excitation energy transfer of the collisional process7Li*(2P 1/2+Cs(6S 1/2)→7Li*(2P 3/2)+Cs(6S 1/2) have been measured. The experimental cross sections, σLi-Cs (1/2→3/2)=890 Å2 and σLi-Cs (3/2→1/2)=430 Å2, are compared with theoretical data obtained by a sudden impact approximation approach taking into account the long-range interaction potentials only. The calculated cross sections show an excitation mixing process at large internuclear distances where Li-Cs dipole-dipole and dipole- quadrupole interaction forces are predominant.
