| Research Abstract |
Spin-isospin responses in highly excited state of nucleus are studied by the exothermic charge-exchange(CE) reaction with unstable beam in the time-like region. To realize the study the high resolution magnetic spectrometer SHARAQ was designed and constructed. The SHARAQ was installed in the RIBF of RIKEN Nishina Center. A search for a new spin mode was made and theβ+ isovector spin monopole resonance was found. The nuclear matrix elements(NME) for the 2v2βdecay, ^<48>Ca and ^<116>Cd, were studied by the (p,n) and (n,p) reactions. Obtained NMEs will play a decisive role in the determination of neutrino mass once 0v2β decay were found.
