Inelastic differential scattering of electrons by hydrogen atoms from 0.75-4 Ryd: n=2 states

Differential cross sections for excitation of the n=2 states of atomic hydrogen by electron impact are calculated in a hybrid pseudostate close-coupling distorted-wave model at energies from 13.6 to 54.4 eV. The total (2s+2p) differential cross sections are in good agreement with absolute measurements. Elastic differential cross sections are given at 54.4 eV. Sets of parameters which give a complete description of the radiative decay of the excited 2p state and of the angular distribution of the scattered electron are presented for four energies with a view to simulating coincidence experiments.
