Br. Odgers et al., ELECTRON-SCATTERING FROM HYDROGEN-ATOMS AT INTERMEDIATE ENERGIES - INTEGRATED CROSS-SECTIONS TO N = 3 LEVELS, Journal of physics. B, Atomic molecular and optical physics, 27(12), 1994, pp. 2577-2584
A modified version of the IERM approach is applied to electron scatter
ing from hydrogen atoms at intermediate energies to evaluate integrate
d cross sections for the n = 2 to n = 3 transitions. Results are compa
red with earlier work which overestimates these cross sections due to
the omission of continuum channels. These results have important appli
cations in astrophysics.
