Abstract
The first observation of the double-charge-exchange reaction () to discrete nuclear states is reported. The mass of has been measured using the reaction at MeV. The reaction , with known MeV, was used as the calibration reaction to obtain MeV for the reaction . The mass excess of is thus found to be 24.91(15) MeV.
