Abstract

Experimental and theoretical cross sections for the excitation of ground-state lithium by Hf and He2+ impact are presented for the 2-30 keV/amu energy regime. Li(2s) excitation up to the Li(n = 4) level was simulated by means of the atomic-orbital close-coupling method. Experimentally, absolute emission cross sections were determined by observing the LiI(nd-2p,n = 3-6) and LiI(ns-2p,n = 4-6) line radiation after ion impact. Furthermore, a few measurements have been performed on high-n excitation [Li(2s-->nd,n = 7-9)] by He2+ impact. [S1050-2947(99)06912-7].
