Abstract：
Angular distributions of the elastic and inelastic scattering of ¹⁸O+¹⁴⁸Nd at 90.72 MeV were measured by using the Q3D magnetic spectrometer as well as the focal plane detector system. The experimental results were reproduced by DWBA and Coupled Reaction Channel calculation code FRESCO. The polarized potential was introduced in the DWBA calculation and the similar results with the Coupled Channel calculation were obtained. The interference effect of nuclear-Coulomb in the inelastic exciting was discussed and the approximate factor describing the interference intensity were reduced.
