show the versatility of the code in its good agreement to available data. The neutron deficient p-nuclei,
shielded from neutron capture, are mainly synthesized by photodisintegration reactions. In the hot (T9 =
2-3) photon bath where they are produced, there is a reprocessing of initial s-seed [3] material. In the lab,
it is often the capture reaction that is measured. Although the trends for the (nγ,) cross section curves
are similar for the experimental and evaluated, deviations (in the resonance range) occur. The situation
has traditionally been worse for the α-capture data. One possibility for the discrepancy could arise from
the α-optical potential. In order to correctly model the abundances (such as p-process simulations which
consider about 20,000 reactions), accurate cross sections are required for reaction rate calculations. The
calculated cross sections and S-factors (whose treatment has been recently implemented into EMPIRE)
for 102 Pd(p,γ) , 120 Te(α,n),(p,n),(p,γ), 130 Ba(α,γ),(α,n), 190 Pt(n,γ) (no S-factor) and 92 Mo[4](α,n) will be
compared to available data.

The Nuclear Shell Model and Nuclear Data
B. Alex Brown
Michigan State University
I will present an overview of results obtained with the configuration interaction (CI), shell-model, approach
to nuclear structure. The talk will focus on which regions of the nuclear chart and what types of nuclear
data can be considered. The present status of NuShellX@MSU will be shown. The NuShellX code was
written by W. D. M. Rae (Garsington, England). NuShellX@MSU includes wrapper codes for model space
and Hamiltonian inputs, and outputs that include graphical comparisons to data form the nuclear data
base.

A new generation of ab-initio calculations, based on realistic two- and three-body forces, is having a
profound impact on our view of how nuclei work. They can address issues surrounding the topology of the
mean field, the origin of effective forces (like the spin-orbit interaction and tensor forces) and the causes of
cluster and pairing correlations. To improve the numerical methods, and the parameterization of 3-body
forces, new precise data are needed. Measurements of mass and RMS radii probe the static properties of
