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

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