Abstract

The ¹¹⁶Cd(p,n) experiment at 300 MeV has been performed for deducing the Gamow-Teller (GT) transition strengths B(GT^-) in ¹¹⁶In. For the transition to the ground state, the B(GT^-) value of 0.26 ± 0.02 is obtained. From this B(GT^-) value and the B(GT⁺) value by a beta-decay experiment, the contribution of the intermediate ground state of ¹¹⁶In to the nuclear matrix element is deduced to be 0.070 ± 0.003. The B(GT^-) value obtained herein is a factor of 8 less than that obtained from a previous (³He,t) measurement. This discrepancy, as well as differences in the distribution of low energy GT strength, and the width and peak energy of the GT giant resonance may be explained if the target used in the (³He,t) measurement is a Cd target with natural abundance.
