Possible Mechanism of Atomic Disintegration

THE experiments of atomic disintegration (Rutherford, Chadwick, Kirsch, Pettersen, Kara-Michailova, Bieler, etc.) show that by bombardment of α-particles it is possible to obtain hydrogen emission. Taking the case of heavy atoms, with big nuclear charges, if the α-particle cannot reach the nucleus, then hydrogen must come from the more external part of the atom.
