Abstract

The effect of initial vibrational excitation on Li2(n,J) + Na collisions was studied exptl. and theor. The relative integral cross sections s(n,J) were measured in a crossed beam expt. for vibrational states n populated thermally or by optical pumping, and for final states detected by laser induced fluorescence. It is found that s(n,J) increases by 35 +- 7% between n = 0 and n = 20, while the ...
