Abstract

The widths which along with the centroids define the strength distributions for the subspaces of a given (mJT) space are found to be clustered within a narrow range of values. Approximations to the fixed-JT averaging spectral distribution method based on this factor are suggested and their accuracies discussed. Using these approximations, one can now perform nuclear structure calculations in a large model space with good accuracy and at a relatively low cost.
