Energy Dependence of Fine Structure Transition Cross Section for K(4P) - He, H sub 2 Collisions in the Range 0.1 - 0.4 EV

摘要

The energy dependence of the cross section has been measured for the following processes K(4 exp 2 Psub(1/2)) + X reversible K(4 exp 2 Psub(3/2)) + X when X is a rare gas atom or a molecule. A crossed beam technique associated with a laser light excitation of the alkali is used. The fluorescent light inensities coming from Psub(1/2) and Psub(3/2) levels are measured to give the corresponding populations. (Atomindex citation 12:633397)
