|Title:||Electron collisions with the hydrides PH3, AsH3 and SbH3|
|Abstract:||We report integral cross sections for the elastic scattering of low-energy electrons by the hydrides PH3, AsH3 and SbH3. To calculate the cross sections, we employed the Schwinger multichannel method with pseudopotentials (Bettega et al 1993 Phys. Rev. A 47 1111) at the static-exchange plus polarization level of approximation for incident energies from 0.5 to 8 eV. For PH3, we compare our integral cross section with the recent total cross section measured by Szmytkowski et at (2004 J. Phys. B: At. Mol. Opt. Phys. 37 1833) and find good agreement in shape. In particular, our calculated elastic integral cross section for PH3 also shows the two structures reported by the experiment. We have found that the three hydrides present a Ramsauer-Townsend minimum at around 1 eV.|
