Spin‐isospin (Gamow‐Teller) excitations in 64 Cu and 64Co have been studied using (3He,t) and (d,2He) charge‐exchange reactions on 64 Ni. As the isospin of the 64 Ni ground‐state is T 0=4, states with T=3, 4 and 5 in 64 Cu 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 64 Cu 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 64 Cu 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 64 Ni in a consistent way.
