Abstract

The (d $,^{2}$ He) reactions on light nuclei were studied at $E_{d}$ =260 MeV with a large solid-angle, wide momentum-acceptance spectrometer. The data indicated the direct one-step nature of the reaction at this energy. Observed excitation-energy spectra for N=Z nuclei compared well with those from the (p,n) reactions at similar momentum transfer. The peaks corresponding to the $0^{+}$ → $1^{+}$ transitions showed angle dependence characteristic of ΔL=0. The 0° (d $,^{2}$ He) cross sections were found to be proportional to the Gamow-Teller β-decay strengths.
