Abstract
We performed quasiresonant laser excitation of Li-Cd vapor mixtures at 460. 3 nm (2p-4d) and 497.2 nm (2p-4s). The initial population of the Li(2p) lev el is caused by three processes: collisional dissociation or photodissociat ion of the Li-2(B-1 IIu) molecules or energy transfer in Li-2(B-1 IIu) and Li(2s) collisions. The Li(4d,4s) atoms radiatively decay towards Li(3p), fr om which collisional population transfer to Cd(5(3)P(J)) occurs, followed b y three-body reactive collisions which produce the LiCd(2(2)II) excimer sta tes.
