Proton neutron emission model for Muon charge exchange reaction

Ordinary µ capture is useful for probing the neutrino nuclear responses for double beta decay especially in the β+ side region. The aim of this study is to measure the prompt and delayed gamma rays from NatMo (µ,xnv) and 100Mo (µ,xnv) reactions and calculate the relative capture strength, β(µ,E) using the Proton-Neutron Emission Model (PNEM). Experimental data of NatMo and 100Mo targets irradiated by negative µ at MuSIC Facility, Osaka University are analysed and the production rates, and the mass distribution were obtained. The experimental data was compared with the mass distribution calculation using PNEM to get the β(µ,E). The giant resonance (GR) like distribution was observed with the first GR peak around 12 MeV.
