Theoretical work by Tweed (J. Phys. B.: Atom. Molec. Phys.; 6: 259 and 270 (1973)) on double ionization of helium-like atoms by high energy electron impact has thrown doubt on previous theoretical (Byron and Joachain, Phys. Lett.; 24A: 616 (1967) and Phys. Rev.; 164: 1 (1967)) and experimental (van der Wiel and Wiebes, Physica; 54: 411 (1971)) work on this problem. indeed, Tweed has argued that a consistent neglect'' of exchange leads to: a factor of three difference between his high energy results and those of Dyron and Joachain who used the first Born approximation to analyze this problem, a renormalization'' by the same factor of the experimental data of Van der Wiel and (UK)
