ELECTRON SPECTRA OF THE COLLISIONS Н¯(D¯) +НЕ

The present work is aimed at the theoretical study detachment of electron in collision of negative ion hydrogen (deuterium) and atom helium for collision energy range between 2 and 100 eV. The detached electrons are distributed with a very narrow distribution at low collision energies and a wider distribution as the collision energy increases. The results obtained are in agreement with experimental data.
