We extend our previous studies of the neutrino-induced reactions on 12 C and muon capture to include partial occupation of nuclear subshells in the framework of the continuum random phase approximation. We find, in contrast to the work by Auerbach et al., that a partial occupation of the p 1/2 subshell reduces the inclusive cross sections only slightly. The extended model describes the muon capture rate and the 12
