Unitary-Model-Operator Approach to Nuclear-Structure Physics. I

Abstract

A discussion of the unitary-model-operator approach to the correlation problem in nuclei is presented and some calculational detials are discussed. The renormalization of the tensor force is carried out in second-order perturbation theory after the introduction of a set of correlated basis functions. It is indicated that the application of the Hartree-Fock method to the resulting effective Hamiltonian extends the range of application of the theory for which a degree of self-consistency in the calculations may be achieved.
