Excitation of the ( 2 p 2 ) 1 D and ( 2 s 2 p ) 1 P autoionizing states of helium by 200 eV electron impact

Abstract

We report full second Born calculations with inclusion of post-collision interactions for excitation of the (2p2)1D and (2s2p)1P autoionizing states of helium by 200 eV electron impact. The calculations are compared to (e, 2e) measurements of McDonald and Crowe (McDonald D G and Crowe A 1993 J. Phys. B: At. Mol. Opt. Phys. 26 2887–97) and Lower and Weigold… (More)
