Nuclear Experiment 2017-03-27 v1

Abstract

The (11^{11}B,11^{11}Li) double charge-exchange reaction (DCER) at E(11E(^{11}B)/AA=80 MeV was measured for the first time to demonstrate the feasibility of the reaction for studying neutrino nuclear responses for double beta decays (DBD). The 13^{13}C(11^{11}B,11^{11}Li)13^{13}O reaction shows strengths at the ground state and low and high excitation giant resonance regions. The 56^{56}Fe (11^{11}B,11^{11}Li) 56^{56}Ni reaction shows the large strengths in the possible double giant resonance region and beyond, but shows no strengths in the low excitation region below 5 MeV, suggesting strong concentration of the DBD strength at the high excitation region. The DCER is used to evaluate the spin isospin strengths relevant to DBD responses.
