FRAPICCINI, A. L.; RODRIGUEZ, K. V.; GASANEO, G. and OTRANTO, S.. Electron impact single ionization of the He-isoelectronic sequence. Braz. J. Phys. [online]. 2007, vol.37, n.3b, pp. 1115-1120. ISSN 0103-9733. http://dx.doi.org/10.1590/S0103-97332007000700007.
In this work, triply differential cross sections for single electron emission due to electron impact on the He-isoelectronic sequence are calculated by using a Born-C3 model. The influence of the nuclear charge on the angular distributions is analyzed. The validity of a scaling law initially derived in the framework of photo-double-ionization is discussed.
