摘　　要：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 tbe elastic and inelastic scattering cross sections. Two cboices 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.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）.
