The rate of the muon capture reaction μ-+He3→H3+ v, the angular distributionand the polarization of the final nucleus H3 are calculated basing on the universal V- A coupling with induced pseudoscular term and the weak magnetic current included. A general initial condition with polarized muon and polarized He3 nucleus in different hyperfine states is assumed.The ground state wave function is assumed to be a pure S-state. Thus we neglected the contribution of other states, which may be caused by the presence of tensor force or other velocity dependent forces. Meson exchange current is also neglected. Under these assumptions we have proved that the capture amplitude contains only one unknown nuclear matrix element, which is the Fourier transform of the nuclear density function. To determine this nuclear matrix element by the scattering of electron (or muon) with He3 (H3) nucleus is finally proposed.
