Description
The isobaric single charge-exchange reactions, which are determined directly by the Fermi transition ($\Delta L = 0, \Delta S = 0, \Delta T = 1$) between the isobaric analog state (IAS) and the ground state of target, can be used as a tool to study bulk properties of nuclear matter and probed the neutron skin thickness in heavy nucleus. In this work, the ($^3$He,$t$)IAS reactions are studied within the framework of Lane model. The folding model using the Argonne v18 $G$-matrix interaction derived from Brueckner--Hartree--Fock calculation is used to determine the microscopic nucleus-nucleus optical potential. The insight of the in-medium nucleon-nucleon interaction plays a key role in the study of some properties in nuclear matter such as symmetry energy, especially nuclear astrophysical aspects of neutron stars, core-collapse supernova, and kilonova. The results indicate that the density-isospin dependence of the $G$-matrices play a non-negligible role in the description of the experimental data.
