15-stateR-matrix investigation of resonances in the inelastic scattering of electrons from atomic hydrogen at energies up to 13.06 eV

A 15-state R-matrix calculation has been carried out at 530 energies ranging from the n=2 threshold up to n=5 threshold at 13.06 eV to map out the resonant profiles for the n=2 inelastic integral and differential cross sections, and the angular distribution of the spin asymmetry in the inelastic scattering of spin-polarized electrons by the spin-polarized hydrogen atoms at angles 0^∘{}, 30^∘{}, 55^∘{}, 70^∘{}, 90^∘{}, 125^∘{}, and 180^∘{} for the 1s{→}2s transition. The calculations are compared with the experiments and the feasibility studies of using the electron-energy-loss experiments in the investigation of resonances with positions higher than the n=2 threshold have been carried out.
