DIRAC'S wave equation for the electron involves a Hamiltonian linear in the momenta pk. This fact seems to be of geometrical nature and suggests the introduction of a linear fundamental differential… Expand

DR. J. CHADWICK'S explanation1 of the mysterious beryllium radiation is very attractive to theoretical physicists. Is it not possible to admit that neutrons play also an important rôle in the… Expand

THE well-known mass defect curve of the old nuclear scheme calculated with regard to α-particles and protons presented a difficulty with its minimum of binding energy for tin and an increasing… Expand

As electrons and positrons are expelled in some reactions from nuclei, we can try to treat these light particles like the photons emitted by atoms. Then the interaction of heavy particles (protons,… Expand

ZusammenfassungEs wird gezeigt, da\ man die Wechselwirkung der schweren Kernteilchen1) berechnen kann, wenn sie durch leichte Teilchen übertragen ist. Die verschiedenen Gesetze der Wechselwirkung, z.… Expand

IT is known that, starting with Fermi's expression for the coupling between a heavy nuclear particle and the field of electrons and neutrinos, we get in the second approximation the law for… Expand
