The mu-capture process on He-3 leading to a neutron, a deuteron, and a mu-n
eutrino in the final state is studied. Three-nucleon Faddeev wave functions
for the initial He-3 bound and the final neutron-deuteron scattering state
s are calculated using the Bonn B and Paris nucleon-nucleon potentials. The
nuclear weak current operator is restricted to the impulse approximation.
Large effects on the decay rates of the final state interaction are found.
The comparison to recent experimental data shows that the inclusion of fina
l state interactions drastically improves the description of the data. [S05
