Generalized hybrid derivative coupling model for finite nuclei

The generalized hybrid derivative coupling model has been applied to explor e various ground state properties of different nuclei. In this work we have confined our calculation only to the model characterized by the hybridizat ion parameter alpha = 1/4 which gives better results than the other models of the same class, as we have seen earlier, for nuclear matter calculations . The binding energy, single-particle energy spectra, density and charge ra dii of different doubly closed nuclei like O-16, Ca-40, Ca-48, Zr-90, Sn-13 2, Pb-208 have been studied. The success of this model, in describing the d oubly closed nuclei, motivates us to extend this calculation further in the case of open shell nuclei after incorporating the pairing interaction and using a BCS transformation. We have calculated the binding energy for such nuclei. Mie have also studied the isotopic shift for different Pb isotopes with respect to Pb-208. We have compared our results with the other standar d theoretical results as well as with the experimental values.
