Sažetak
Applying resonant Doppler-free 2-photon laser spectroscopy with thermionic diode detection, the cross sections for the excitation energy transfer of the collisional process 7Li*(2P1/2)+Cs(6S1/2)->7Li*(2P3/2)+Cs(6S1/2) have been measured. The experimental cross sections, Li-Cs (1/2->3/2)=890 &Aring ; ; ; 2 and Li-Cs (3/2->1/2)=430 &Aring ; ; ; 2, 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.
