Abstract : The possibility is examined of spontaneous symmetry breakdowns in the electrodynamics of two originally identical charged fields with minimal coupling. The analysis provides a simple example of internal symmetry, SU(2), for which three possibilities arise: (1) no spontaneous breakdowns occur and the vacuum state possesses full SU(2) invariance; (2) a partial breakdown occurs which will be seen to produce a mass splitting out of muon to e+gamma-ray decay; and (3) full SU(2) breakdown occurs which will result, in general, in allowed muon to e+gamma-ray decay as well as mass splitting. Only minimal gauge invariant interactions are involved, and hence divergencies and cut off problems are avoided. (Author)
