abstract: The NSCL charge-exchange group has ongoing programs to measure the spin-isospin response of nuclei. This talk will focus on measurements of the 150Sm(t,3He)150Pm* and 150Nd(3He,t)150Pm* reactions, which are essential for studies of the two-neutrino and zero-neutrino double beta (0) decay of 150Nd. 150Nd is one of the main candidates for 0 decay detection experiments. Accurate nuclear matrix elements are needed to design detectors for 0 decay and to extract information about the neutrino mass scale and hierarchy from resulting experimental data. Nuclear charge-exchange experiments play an important role in constraining the theories used to predict these matrix elements by providing Gamow-Teller and higher order multipole transition strengths to the virtual intermediate nucleus. In addition to its applications for 0 decay, investigation of the spin-isospin response of heavy, deformed nuclei is important for future work on rare isotopes.
