Abstract
A multichannel extension of a hybrid algebraic variational method, first suggested by Oberoi and Nesbet (1973), is described in detail. It is used to carry out a systematic study of the effects of various choices of target-state bases (which may contain pseudostates) and correlation terms on inelastic (e-, He+) scattering cross sections near the n=2 threshold. Results are also obtained for electron scattering by Li2+, C5+ and Ne9+ at two energies using a 13-state basis and are compared with results obtained in the 3- and 6-state close-coupling approximations.Keywords
