Abstract

Spin-isospin (Gamow-Teller) excitations in 64Cu and 64Co have been studied using ( 3He,t) and (d, 2He) charge-exchange reactions on 64Ni. As the isospin of the 64Ni ground-state is T 0=4, states with T=3, 4 and 5 in 64Cu are excited via the ( 3He,t) reaction and states with T=5 in 64Co via (d, 2He). If we assume that the nuclear interaction is charge symmetric, the T=5 states in 64Cu should appear at corresponding excitation energies (if corrected for the Coulomb displacement) and with similar strengths as the T=5 states in 64Co. As in the 64Cu spectrum the T=5 states are very weakly excited, only by combining the results of the two complementary experiments one can estimate the Gamow-Teller strength starting from 64Ni in a consistent way.
