Abstract

The total cross section for simultaneous ionization–excitation of helium by electron impact has been revisited within the framework of the fully nonperturbative B-spline R-matrix with pseudostates approach. A long-standing discrepancy regarding the absolute normalization of the cross section for ionization with simultaneous excitation of the residual ion into the He+(2p) is resolved in favour of the values suggested by Bloemen et al (1981 J. Phys. B: At. Mol. Phys. 14 717) and Forand et al (1985 J. Phys. B: At. Mol. Phys. 18 1409) rather than the renormalization proposed by Merabet et al (2003 J. Phys. B: At. Mol. Opt. Phys. 36 3383).
