Abstract
Using random two-body interactions between valence space nucleons, I calcul ate various statistical measures of the many-body wave functions obtained f rom diagonalization. These measures include the entropy, spectral rigidity, and the inverse participation ratio. From these calculations: I find that the various random ensembles exhibit quite similar spectral characteristics . These characteristics are similar to those obtained from realistic intera ctions.
