Microscopic analysis of the differential cross section for 18O + 76Se elastic and inelastic scattering at energy 275 MeV in the framework of the optical model is presented. For the inelastic scattering, the distorted wave Born approximation (DWBA) and coupled channel (CC) approaches are taking into account to calculate the effect of the low-lying states, 0+ and 2+ for the two interacting nuclei, and their mutual excitation (2+, 2+). Two microscopic potentials are constructed based upon the single Yukawa S1Y and the density independent M3Y nucleon-nucleon interactions using double folding model, in addition to the complex phenomenological Woods-Saxon potential. Although the two microscopic potentials are used without any reduction factors, the S1Y potential described the data over all the angular range better compared to M3Ypotential. A small effect of the single excited channel of target and a relevant effect for mutual excitation on the elastic cross section are found. The success of S1Y potential in describing the data makes it promising in explaining the double charge exchange reactions.
