Abstract :
In this study, coupling between capacity nucleon and nuclei core vibrations in the Pb 208 nuclei are discussed. Hamiltonian matrix was formed on the basis of particle-vibration for each level and was fitted after diagonalization using experimental levels. Therefore, a set of corrected experimental levels obtained which are pure single-particle. Results show that the neutron and proton energy gaps are getting bigger by 0.81 MeV and 0.39 MeV in the corrected spectrum, respectively. Woods-Saxon Phenomenological Potential Codes are then optimized for reproducing the corrected levels. As a result, calculated levels using new WS potential quantities have the best matching experiences compared to the previous studies.
