Abstract

A nuclear shell model was used to compare the realistic interaction with random interactions obtained for various ensembles of random matrix elements. The model with effective two-body forces in a restricted Hilbert space calculated the properties of ground and low lying eigen states. The shell-model calculations demonstrated the existence of a set of single-particle energies and two-body interaction matrix. It was found that the the overlap of ground states with realistic wave functions was very small in average although quantum numbers of those states in even-even nuclie had a high probability.
