Abstract
Ordinary muon capture (OMC) on enriched isotopes was studied for the first time to investigate neutrino nuclear responses for neutrinoless double- decays and supernova neutrino nuclear interactions. Muon capture on proceeds mainly as with being the number of neutrons emitted from negative muon capture. The Nb isotope mass distribution was obtained by measuring delayed rays from radioactive . By using the neutron emission model after the muon capture, the neutrino response (the strength distribution) for OMC was derived. The OMC strength distribution shows a giant resonance (GR) at the peak energy around 11–14 MeV, suggesting the concentration of the OMC strength at the muon GR region.
