Abstract

Experimental and theoretical differential cross sections (DCS) for the electron-impact excitation of molecular hydrogen to the B S+u 1 sc Pu 3 sa S+g 3 sC Pu 1 sand the E(F) S+g 1 states are presented at incident energies near to threshold. The experimental DCSs were taken at incident energies of 14, 15, 16 and 17.5 eV and for scattering angles from 10° to 130°. The theoretical DCSs are from the convergent close-coupling method which has recently successfully modeled differential electron scattering from H2 when compared with available experiment at energies of 17.5 eV and above.
