Abstract
Angular correlation parameters and differential cross sections are calculated in the distorted-wave approximation for 40–200-eV electron impact excitation of the 2′P state of helium. Initial- and final-channel distorted waves are calculated as eigenfunctions of a complex optical potential. The optical potential consists of a static Hartree-Fock atomic potential, a polarization potential term, an exchange distortion term, and an imaginary term representing electron absorption into other open channels. The appropriate inelastic scattering T matrix is obtained for non-Hermitian operators. Effects of polarization, exchange, and absorption are examined individually and collectively and the results are compared with experimental data.
