STATIC-EXCHANGE CROSS-SECTIONS FOR ELECTRON-COLLISIONS WITH B2H6, C2H6, SI2H6, AND GE2H6

We report integral and differential cross sections from 5-30 eV for el astic scattering of electrons by X2H6 (X=B, C, Si, Ge) obtained using the Schwinger Multichannel Method with Pseudopotentials [M.K.F. Betteg a, L.G. Ferreira, M.A.P. Lima, Phys. Rev. A 47, 1111 (1993)]. We compa re our results with available experimental data and other theoretical results, and also with previous results for XH4 (X=C, Si, Ge) [M.H.F. Bettega, A.P.P. Natalense, M.A.P. Lime, L.G. Ferreira, J. Chem. Phys. 103, 10566 (1995)]. To our knowledge this is the first ab initio calcu lation of the B2H6 and Ge2H5 electron scattering cross sections.
