15-STATE R-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 r anging from the n =2 threshold up to n = 5 threshold at 13.06 eV to ma p out the resonant profiles for the n = 2 inelastic integral and diffe rential cross sections, and the angular distribution of the spin asymm etry in the inelastic scattering of spin-polarized electrons by the sp in-polarized hydrogen atoms at angles 0-degrees, 30-degrees, 55-degree s, 70-degrees, 90-degrees, 125-degrees, and 180-degrees 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.
