It is pointed out that direct evidence bearing on the four fermion interaction in mu -capture can be obtained by measuring the angular distribution of recoils relative to the mu -polarization. The existence of an anisotropy implies parity and charge conjugation breakdown. The sign of the anisotropy coefficient yields directly the relative helicities of neutrino and mu meson at creation, The angular distribution is calculated for 0 yields J transitions with parity change (-)J+1 since tals description corresponds to the most practical possibilities; capture in C/sup 12/ and O/sup 16/ The anisotropy coefficient is alpha P where P approximately 0.15 is the mu polarization and - alpha varies between 0.40 and 0.80 for C (between 0.22 and 0.73 for O) depending on the presumed existence of effective pseudoscalar and conserved vector current contributions to the interaction Hamiltonian, (auth)
