An ab initio calculation, following a hyperspherical partial-wave method [J. N. Das, Aust. J. Phys. 47, 743 (1994)], satisfactorily represents the recent experimental triple differential cross-section results of Röder et al. [Phys. Rev. A 53, 225 (1996)] for electron hydrogen atom ionization collisions at low energies. The qualitative agreement with their theoretical results is also good. Moreover, our results are in absolute units and in some instances our results are in better agreement with the experiments compared to their theoretical results. Here it is also exhibited that the hyperspherical partial wave method is a promising formalism for studying atomic ionization problems. © 1997 The American Physical Society.
