Low-energy electron scattering by N, P, As and Sb

We report elastic integral, momentum transfer and differential cross sections from 10-30 eV for electron scattering by (X = N, P, As, Sb). These results were obtained at the static-exchange approximation with the Schwinger Multichannel Method with Pseudopotentials [M H F Bettega, L G Ferreira and M A P Lima 1993 Phys. Rev. A 47 1111]. Our results for are in good agreement with experimental data. We also compare our results with previous calculations on (X = P, As, Sb) [M H F Bettega, M A P Lima and L G Ferreira 1996 J. Chem. Phys. 105 1029] and found, as expected, that the cross sections are larger than the corresponding cross sections.
