Bound Electron

There are two distinct processes by means of which a positron may be annihilated and the excess energy liberated in the form of radiation. These are: (1) Annihilation by a free electron. Here the energy must reappear in the form of at least two quanta to satisfy the conservation laws. (2) Annihilation by a bound electron. In this case the energy may appear in the form of a single quantum since the nucleus of the atom in which the electron is bound is available to take up excess momentum.

Bound Electron

A new unambiguous (unified nonrelativistic-relativistic) renormalization method, going beyond the conventional one, is formulated. Without introducing any artifical mass (or energy) counter-terms in the Hamiltonian, the terms stemming from the experimentally unobservable interaction of the free electron (and fermionic vacuum) with the vacuum radiation field are directly identified and completely eliminated in the corresponding equations of motion for the bound electron.
