Abstract:

The new method presented by B. Brémond and J. G. Valatin is generalized which attached four body correlation to the Bogoliubov transformation. The generalization carried in this paper is similar to that from the Bogoliubov transformation to the generalized Bogoliubov one. We find a criterion of whether a trial ground state vector has an essential feature of four body correlation or it is like that of the generalized Bogoliubov transformation.
This method is applied to a system with a charge independent pairing interaction. There appear two different kinds of single quasiparticle excitation energy due to proton-neutron interaction.
