The problem of the behavior of positrons and electrons in given external potentials, neglecting their mutual interaction, is analyzed by replacing the theory of holes by a reinterpretation of the solutions of the Dirac equation. It is possible to write down a complete solution of the problem in terms of boundary conditions on the wave function, and this solution contains automatically all the possibilities of virtual (and real) pair formation and annihilation together with the ordinary… 
Lagrangian Formulation and Green Functions
In the preceding chapters the theory of Dirac particles has been developed extensively, and a variety of applications carried out. But most of these model problems consisted of the electron or
Theory of Radiation
Recent developments in the theory of radiation have brought this subject to a very complete state. There is a nearly closed domain, in which the interaction between charged particles and the
Anomalous radiative transitions
Anomalous transitions involving photons derived by many-body interaction of the form, @µG µ , in the standard model are studied. This does not affect the equation of motion in the bulk, but makes
Massless Composite Bosons Formed by the Coupled Electron-Positron Pairs and Two-Photon Angular Correlations in the Colliding Beam Reaction e-e+→Bγγ with Emission of the Massless Boson
The approach in which the electron and positron are treated as ordinary, different particles, each being characterized by the complete set of the Dirac plane waves, is examined. This completely
A Survey of Field Theory
These six articles attempt to summarize the concepts and results of the field theory of elementary particles in terms which, it is hoped, will be understood by experimentalists or theoretical
Nucleon-nucleon scattering at high energy
SummaryThe nucleon-nucleon scattering and polarization experiments cannot be explained by a simple local potential. This method gives good results in the low energy domain. But between 0 and 300 MeV,
The external field approximation of quantum electrodynamics
The quantized field description of particles interacting only with a given unquantized (i.e., external) field is related in a simple way to the one-particle s matrix. Here s is based upon the
