Abstract

In 1910, by catching at the instant of ionization the positive residues of atoms ionized by X-rays, and by beta and gamma rays of radium, it was conclusively shown(2) that the act of ionization by these agencies uniformly consists in the detachment of a single negative electron from a neutral atom.
