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 elastic scattering of electrons by X2H6 (X=B, C, Si, Ge) obtained using the Schwinger Multichannel Method with Pseudopotentials [M.K.F. Bettega, L.G. Ferreira, M.A.P. Lima, Phys. Rev. A 47, 1111 (1993)]. We compare 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 calculation of the B2H6 and Ge2H5 electron scattering cross sections.
