   From the analyzes of a differential crossection of electrons elastic scattering on the hydrogen-like atoms in an external electric field the "fitting" parameters to the ionization crossections of a hydrogen atom in a such field are determined. It was shown that in the energy region of primary and secondary electrons, corresponding to their reflections from potential barrier of external field, a sharp peak in the angular momentum distributions of scattering and secondary electrons appears. At the same time, these distributions are oscillating and the crossection regarding to the unity of the secondary electrons momentum may be much higher than the corresponding ionization crossection of an isolated atom.
