Abstract: Spin-isospin excitations in nuclei have been studied by means of the (3He,t) reactions at 450 MeV. The Gamow-Teller (GT) resonances are found to be strongly excited. A fine structure of the giant Gamow Teller resonances in medium-heavy nuclei is observed with an energy resolution of 130 keV. The volume integrals of the effective interactions J[sigma][tau] and J[tau] have been determined experimentally. The importance of high resolution observation of the (3He,t) reactions at intermediate energies, both, to study the double [beta] decay processes and to measure the detection sensitivities for solar neutrino experiments is discussed.
