Description

We performed a missing mass spectroscopy at RIBF using double charge exchange reaction ${}^{48}$Ca(${}^{12}$C, ${}^{12}$Be(0${}_2^{+}$)), aiming for the observation of the double Gamow-Teller giant resonance. We observed some structures in the excitation energy spectrum of ${}^{48}$Ti at the energy region where the double Gamow-Teller giant resonance is expected to exist. We compared the experimental angular distribution to the theoretical calculation. The present status of the analysis will be reported.
