Abstract Precise determination of the four coupling constants describing the parity-odd neutral current interaction between muon and nucleons would provide a critical test of the standard model. The directional correlation between the photon emitted in the transition between 2S- and 1S-states and the decay electron provides a suitable observable. The two isotopes of boron constitute a unique system for a complete determination of the coupling constants. Completeness requires that the hyperfine components of the initial or final state of the photon transition be distinguished. An elegant method of measuring the directional correlations in the hyperfine components of the final state is the Fourier analysis of the muon spin precession in correlation with the emitted photon radiation. The purpose of this paper is to derive the relationship between the directional correlations and the coupling constants, determine optimal energy and angular intervals for a measurement, and discuss the experimental issues which must be resolved in preparation of an experiment.
