Measurements have been made of the 96Zr(p,gamma)97Nb,
112Sn(p,gamma)113Sb, and 119Sn(p,gamma)120Sb cross section excitation
functions. Incident proton energies ranged from 2.8 MeV to 8.5 MeV.
These Reactions are relevant to several processes of stellar
nucleosynthesis. The resulting astrophysical S-factors are compared to
those from statistical model calculations using the SMOKER, and the more
recent NON-SMOKER, codes to judge their applicability to these reactions.
