Investigation of spin-isospin strength in 48Ca-->48Sc and 90Zr-->90Nb using the (6Li,6He) reaction.

Abstract

The ${(}^{6}$Li${,}^{6}$He) reaction was studied on the target nuclei $^{48}\mathrm{Ca}$ and $^{90}\mathrm{Zr}$ at ${\mathit{E}}_{\mathrm{Li}}$=156 MeV at extreme forward reaction angles. From the zero degree spectra Gamow-Teller strength was extracted for excitation energies 0\ensuremath{\le}${\mathit{E}}_{\mathit{x}}$\ensuremath{\lesssim}20 MeV. The results are compared with distorted-wave Born approximation calculations and (p,n) data.
