Abstract：
The experimental data on elastic and inelastic scattering of 270 MeV ³He particles to several low lying states in ⁹⁰Zr, ¹¹⁶Sn and ²⁰⁸Pb are analyzed within the double folding model (DFM). Fermi density distribution (FDD) of target nuclei is used to obtain real potentials with different powers. DF results are introduced into a modified DWUCK4 code to calculate the elastic and inelastic scattering cross sections. Two choices of potentials form factors are used; Woods Saxon (WS) and Woods Saxon Squared (WS²) for real potential, while the imaginary part is taken as phenomenological Woods Saxon (PWS) and phenomenological Woods Saxon Squared (PWS²). This comparison provides information about the similarities and differences of the models used in calculations.
