Description

Excitation transfer between the 3S1/2 states of the lithium isotopes 6Li and 7Li is measured in a thermionic diode. The 3S level is excited by off-resonant two-photon transitions with a single mode cw laser. The relative densities of the directly excited and collisionally populated levels are probed by further laser excitation to the 12P levels. An energy transfer cross section of 585 A2 ± 160 A2 is found at the experimental temperature of about 850 K. A simple semiclassical calculation yields a cross section of 450 A2. (orig.)
