Abstract
Born partial-wave integrals have been performed for a range of energies and total cross sections are presented for electron-hydrogen-atom excitation both in the conventional first Born approximation (Born I) and the unitarised Born approximation (Born II). Exchange effects are not included. With the exception of exact resonance-allowed transitions (n=n', lambda =1) results are presented for all transitions between hydrogen-atom states whose principal quantum number is less than or equal to 4.Keywords
