The ( He, t) charge-exchange reaction has been studied at E( He)=200 MeV and angles near 0 on targets of "Sn and Sn. Fragmentation of the giant Gamow-Teller resonance into separate components of the particle-hole type has been observed in good agreement with theoretical predictions. These components are connected with what is usually referred to in the literature as direct-, core-poLarization-, and back-spin-Bip Gamow-Teller strength. The observed cross sections near 0 = 0' suggest contributions from the isovector spin-Hip interaction as well as the isovector tensor interaction. A theoretically predicted configuration splitting of the main Gamow-Teller component into two components involving the lhiii2 neutron orbital could not uniquely be identified. The data are compatible, though, with such a splitting since the observed widths of the main Gamow-Teller components in Sb and Sb exceed the predicted splittings.
