The existence of the ordinary mu decay, mu yields e + nu + nu (bar), seems to prove that the muon andd electron do not differ in any quantum numbers. It follows that weak electromagnetic transitions between muons and electrons could oecurs if there is a mechanism to produce them. The purpose of this effort is to discuss phenomenologically (without attachment to any specific mechanism other kinds of electromagnetic transitions between muon and electron that may be possible even if mu yields e + gamma is somewhat suppressed.

Weinberg et al. (Wed,) studied this question.
