Abstract : The prior and post Born matrix elements are used to calculate the cross sections for H(-)(1s2) production in hydrogen atom collisions. In contrast to the original version of this work done by Mapleton in 1960, the plane wave approximation to the Coulomb function is partially corrected. The same H(-) wave functions are used, and the post cross sections are substantially unaltered. Cross sections calculated with the improved H(-) wave function as compared with the other H(-) wave functions are from twenty to thirty-five per cent larger for the prior case and twenty to thirty per cent larger for the post case. The post-prior discrepancy, expressed as a ratio, varies between 0.001 and 0.33. (Author)
