| Abstract: | The triple differential cross sections for electron impact ionization of hydrogen at incident energy of 27.2eV in the coplanar asymmetric geometry have been calculated by the modified BBK model. The present results are compared with the experimental measurements, both of them show that the angular distribution of the slow electrons resembles the case of high incident energy, i.e., a binary plus recoil peaks structure, while the BBK model completely fails to repoduce the observed binary peak. |
