In the present solar-neutrino experiments, mainly observing the pp contribution of the solar-neutrino flux, an important role is played by 71Ga. The structure of this detector nucleus and three of its isobars have been calculated by using the microscopic quasiparticle–phonon model. Using a realistic effective two-body interaction in a realistic valence space, the method yielded energy spectra in good agreement with experiments. The calculated logft values for a number of spontaneous and neutrino-induced Gamow–Teller transitions, when compared with the experimental results, gave qualitatively correct but overestimated transition-strength values in most cases.
