Theoretical studies of low-energy electron-silane scatteringwith an ab inition description of target response
PHYSICAL REVIEW A 1992, 45 (9): 6323~6331,-0001,():
Theoretical studies of low-energy electron-silane scattering are reported in whichtarget polarization is included by using an ab intion optical potential. These calculations employ the complex Kohn scattering method and were underkaken both at the static-exchange level and with target polarizatin. Aploarized wirtual-orbital method, which was introduced in our earlier study of electron-methane scattering, was also employedin this study co generate a compact description of the closed channels included in the optical potential. Differential, integral, and momentum-transfer cross sections a Ramsaurer-Townsend minimum at 0.3eV and a broad d-wave shape resonance at 3.0eV. Excellent agreement is found between our polarized Kohn results and the recent experimental resultsof Wan, Moore, and Tosssel[J. Chem. Phys. 91, 7340 (1989)].
