Abstract
The spin-isospin response of nuclei to hadronic probes is discussed. It includes the spin-isospin flip Gamow-Teller excitations at nuclear level and the delta-isobar excitations at nucleonic level. In GT excitations, while the energy dependence of the spin-isospin nucleon-nucleon interaction is understood, the cause for discrepancy between this extracted interaction from the (p, n) data and that coming from the free nucleon-nucleont-matrix is not fully understood. Cause for the observed deficit in the GT-strength with respect to shell model value is also far from settled. For the production of Δ-isobars in nuclear reactions, (3He,t) reaction on proton and12C targets is considered. It is found that the DWBA is a legitimate candidate theory for the description of these reactions.
