A study of e-H ionization is presented at energies ranging from
15.6 to 250 eV. Total through to fully differential cross sections are
calculated using the Convergent Close-Coupling (CCC) method and are
compared with experiment.  We demonstrate that the recent criticism of
our work by Bencze and Chandler is completely unwarranted.
