GLAUBER THEORY OF ATOMIC HYDROGEN EXCITATION BY ELECTRON IMPACT,
Abstract
The Glauber approximation has been applied to excitation of the 2s, 2p, 3s and 3p levels of the hydrogen atom by electron impact. The differential and integrated excitation cross sections predicted by Glauber theory have been compared with experiment and with other calculations. The Glauber approximation is a considerable improvement over the Born approximation at energies < about 100 eV. At energies > about 100 eV the Glauber total excitation cross sections approach the Born, even though at large scattering angles (> 40 deg) the Glauber differential cross sections may be very different from the Born. At intermediate energies (about 30 eV - 100 eV) the Glauber predictions are surprisingly good; at energies < about 20 eV the Glauber integrated cross sections are rather smaller than observed experimentally.
