Description
The 19-state and 29-state R-matrix methods of Fon et al have been extended to calculate the differential cross section (DCS) and electron-impact coherence parameters (EICP) associated with excitation of the 3 1D state of helium for an incident electron energy of 26.5 eV at electron scattering angles ranging from 0-180o. The calculated EICP values are compared with the only experimental data reported recently by McLaughlin et al. The agreement is good. (Author)
