Abstract
Expressions are given for the distribution of electrons emitted in the decay of aligned muons as a function of their energy, direction, and spin. The two-component neutrino theory of Yang and Lee is used, and two cases are considered: (i) neutrino and antineutrino emitted; (ii) two neutrinos emitted. Various correlation terms arise as a result of the inclusion of electron spin. Among these is a time reversal dependent term whose presence would be evinced by asymmetry in a transverse polarization of electrons emitted at right angles to the muon spin.
