Abstract
Excitation transfer between the 3S(1/2) states of the lithium isotopes Li-6 and Li-7 is measured in a thermionic diode. The 3S level is exci ted by off-resonant two-photon transitions with a single mode cw laser . The relative densities of the directly excited and collisionally pop ulated levels are probed by further laser excitation to the 12P levels . An energy transfer cross section of 585 Angstrom(2) +/- 160 Angstrom (2) is found at the experimental temperature of about 850 K. A simple semiclassical calculation yields a cross section of 450 Angstrom(2).
