Collisional excitation transfer between lithium isotopes

  • Published:
Zeitschrift für Physik D Atoms, Molecules and Clusters

Abstract

Excitation transfer between the 3S 1/2 states of the lithium isotopes6Li and7Li is measured in a thermionic diode. The 3S level is excited by off-resonant two-photon transitions with a single mode ew 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 Å2±160 Å2 is found at the experimental temperature of about 850 K. A simple semiclassical calculation yields a cross section of 450 Å2.
