This interaction recently showed success in reproducing observed properties through detailed shell model studies. Spectral distribution studies avoid explicit diagonalization and hold promise for applications to astrophysics.Latex, 19 pages, 1 figure, to be published in Physical Review CNuclear Theorytext
