We have measured cross sections for (d,2He) induced reactions on the p-shell nuclei Li6, C12, and C13 and the sd-shell nucleus Mg24 at an energy of Ed=125.2 MeV. The measured excitation energy spectra are very similar to those from (p,n), (n,p), and (d,2He) reactions at higher energies. The measured 0 (d,2He) cross sections show a remarkably well-defined linear relation with the Gamow-Teller strengths deduced either from decay or from (p,n) reactions. Our results demonstrate that the (d,2He) reaction can be used as a powerful tool to study Gamow-Teller strengths in the + direction at energies as low as Ed=125.2 MeV. 1995 The American Physical Society.
