Abstract
THEORETICAL calculation of the interaction between fast electrons and hydrogen atoms (Bethe, Williams1, etc.) predict an increase of primary ionization when the energy of the incident particle exceeds about one million electron-volts. Wilson chamber experiments have not yet given quantitative results of sufficient precision to ascertain if that increase is real or not.
