1955O. Klein in W. Pauli Niels Bohr 112 Since we are neglecting the interaction between electrons and electromagnetic fields the question of the self-mass does not appear. 1977Dædalus Fall 27 Thus the electron mass found in tables of physical data..would have to be identified with the bare mass plus the infinite ‘self mass’, produced by the interaction of the electron with its own virtual photon cloud. |
