On the possibility of mercury atoms ionization at elastic scattering in experiments on the hyperthermal surface ionization

The dependence of the mercury atoms ionization potential at the recharging critical distance on the flying atoms energy is calculated within the frames of the atoms elastic reflection model. The ionization potential linear dependence on the atoms kinetic energy testifies to the side of the mercury atoms surface ionization model by elastic reflection from the surface. It is established that the ionization process proceeds without participation of the mercury atoms excited states. The degree of the nonequilibrium surface ionization is determined by the surface temperature and reflected neutral particles temperature
