FixedJ spectral distribution in large shell model spaces

II. FixedJ configuration centroids and widths

  • Published:

Abstract

A method is develloped to exactly calculate the fixedJ configuration centroid energies and widths. The resulting approximate level densities for204Pb and020Pb show large departures with respect to the gaussian approximate level densities. The goodness of the polynomial expansion of fixedJ configuration moments is studied and a simple improvement to this approximation is proposed which gives very good results.
