  The transition between isobaric analog states (IAS) in the (3He, t) charge
exchange reaction presents a unique opportunity to access the isospin structure
of the nuclei. In this study not only the Fermi transition but also the
Gamow-Teller (G-T) transition of the IAS reaction were investigated for the
13,14C(3He, t) and 17,18,19,20O(3He, t) reactions, in order to explore the
neutron number dependence of the IAS reaction for the light neutron-rich
nuclei. It was found that the G-T type IAS reaction also exhibited a
significant dependence of the transition strength on the neutron number and the
angular momentum configuration of the nuclei. Additionally, the inverse
kinematics was also discussed for extracting the yields of the interested
reaction channels in the proposed experiments on radioactive beams. The
calculated triton yields demonstrated the capability of the proposed
experiments to obtain meaningful results.
