|Title:||Polarization effects in the elastic scattering of low-energy electrons by XH4 (X=C, Si, Ge, Sn, Pb)|
|Abstract:||We report integral and differential cross sections for elastic scattering of electrons by XH4 (X=C, Si, Ge, Sn, Pb) molecules for energies between 3 and 10 eV. We use the Schwinger multichannel method with pseudopotentials [Bettega , Phys. Rev. A 47, 1111 (1993)] at the static-exchange and static-exchange plus polarization approximations. We compare our results with available theoretical and experimental results and find very good agreement. In particular, our results show Ramsauer-Towsend minima for all XH4 molecules.|
