Electron impact excitation cross sections for allowed transitions in atoms
arXiv:atom-ph/9509006 · doi:10.1103/PhysRevA.53.2425
Abstract
We present a semiempirical Gaunt factor for widely used Van Regemorter formula [Astrophys. J. 136, 906 (1962)] for the case of allowed transitions in atoms with the LS coupling scheme. Cross sections calculated using this Gaunt factor agree with measured cross sections to within the experimental error.
