Abstract

The double-differential cross sections for the 116Cd(p,n) and 116Sn(n,p) reactions were measured at 300 MeV for studying the nuclear matrix element of the 116Cd ββ decay. A multipole decomposition technique was applied to the spectra to extract the Gamow-Teller (GT) component. The integrated GT strengths up to an excitation energy of 30 MeV in the intermediate nucleus 116In are 40±6 and 11±1 in the (p,n) and (n,p) spectra, respectively, including the component from the isovector spin monopole (IVSM). The spectra are compared with those obtained from a theoretical calculation with a quasiparticle random phase approximation, where the contribution from the IVSM component as well as the interference effect between the GT and IVSM components are fully taken into account.
