Description
I present a study of ordinary muon capture on 136Ba, the daughter nucleus of 136Xe double-beta decay, using two independent nuclear structure approaches: the interacting shell model (Jokiniemi code) and a proton–neutron QRPA framework (Ydrefors code). Both calculations employ an exact Dirac muon wave function and cover all relevant multipole contributions to the total capture rate. Within the shell-model approach, the effects of chiral two-body meson-exchange currents on the capture rates are assessed. Differences between the two approaches are discussed in the context of their implications for neutrinoless double-beta decay matrix elements.
