The Dirac Equation,r from being realized on a fundamental level. A great deal of the effort that has been expended in the classical domain is reviewed in the Appendix, where we see that only the nonrelativistic, finite-size model appears to be completely well behaved. [Some recent progress has been booked, however, in

Neutral Fermions and Bosons, which these are associated contain enough other interesing notions that a complete picture cannot be obtained without examining those notions. This chapter, therefore, is devoted to a number of peripheral subjects which, nevertheless, are essential to a full treatment of the Dirac theory.

Further Electromagnetic Interactions,d with the derivation of the bound-state energy levels in a fixed Coulomb field, although it was noted that the picture was not yet complete. For example, there are relativistic corrections to the hyperfine structure which can be obtained by accounting for nuclear mass, spin, and magnetic moment. In

Lagrangian Formulation and Green Functions,odel problems consisted of the electron or positron interacting with an external field, and took no account of the particle’s electromagnetic field. Further understanding can only be achieved by including the radiation field and effects of the self-field acting back on the particle—this is also nece

Quantum Theory of Radiation, major lessons of classical electrodynamics is that accelerated charged particles radiate (though this is not necessarily true for all charge .), and energy conservation alone requires the dynamical equations of motion to account for this phenomenon. Although we have paid lip service to such a requi

The Two-Body Problem,ng the fine structure. And in the preceding chapter we began to achieve an understanding of additional features in the spectrum on a quantitative level. The theoretical treatment is far from complete, however, for there remains considerable fine-tuning of those radiative corrections, as well as vari

Dirac Scattering Theory,in a central potential. In this chapter we shall present a more detailed exposition of relativistic scattering for Dirac particles, various aspects of which apply to any particles. The primary goal is to provide a framework for utilizing the two-body formalism constructed in the preceding chapter, t
