Ordinary muon capture studies for the matrix elements in $\beta\beta$ decay
Abstract
Precise measurement of -rays following ordinary (non-radiative) capture of negative muons by natural Se, Kr, Cd and Sm, as well as isotopically enriched Ti, Se, Kr, Cd and Sm targets was performed by means of HPGe detectors. Energy and time distributions were investigated and total life time of negative muon in different isotopes was deduced. Detailed analysis of -lines intensity allows to extract relative yield of several daughter nuclei and partial rates of (,) capture to numerous excited levels of the Sc, As, Br, Ag and Tc isotopes which are considered to be virtual states of an intermediate odd-odd nucleus in 2-decay of Ca, Ge, Se, Cd and Nd, respectively. These rates are important as an experimental input for the theoretical calculation of the nuclear matrix elements of 2-decay.
