Abstract

In this study, the particle vibration coupling for nuclei around 208Pb addressed. Hamiltonian matrix was constructed on the basis of particle vibration eigenvectors; then, after matrix Diagonalization, fitting with the experimental states was done. Therefore, a set of pure single particle states were obtained which were also called modified experimental levels. The results showed that the neutron and proton energy gap wasconsiderably increased to 0. 81 MeV and 0. 39 MeV in the modified spectrum, respectively. The shell model parameters of phenomenological Woods-Saxon (WS) potential was then adjusted to reproduce these modified experimental states. The results showed that the WS potential could predict the experimental states more precisely with the help of new parameters.
