A GENERALIZED PAIR FIELD APPROACH TO THE SHELL-MODEL

A new approach to the nuclear shell model named as the generalized pair field method (GPFM) is proposed. This method using the optimum pair concept reduces the shell model eigen problems to solving a set of coupled dispersion equations which is tractable even for heavy nuclei. Thus the desired goal of avoiding the dimension difficulty of the traditional shell model approach may be possible. The method can also be applied to a boson system.
