Triple differential cross sections for the ionization of hydrogen atoms by electron impact have been calculated for an incident electron energy of 27.2 eV following hyperspherical partial wave theory for asymmetric geometries. Calculated results are, generally, in good agreement with experiment and with results of some other well known theories. This study clearly indicates that the hyperspherical partial wave theory is a very effective approach for low-energy ionization studies.
