.Cross section measurements of (p,) reactions on the Mo isotopes have
been performed at beam energies from 2 to 6.2 MeV that are relevant to
the p-process. Partial cross sections and isomeric ratios were also
determined for the Mo-92 case. Astrophysical S factors as well as
reaction rates were derived from the experimental cross sections.
Statistical model calculations were performed using the latest version
(1.9) of the statistical model code TALYS and were compared with the new
data. An overall good agreement between theory and experiment was found.
In addition, the effect of different combinations of the nuclear input
parameters entering the stellar reaction-rate calculations was
investigated. It was found that, for certain combinations of
optical-model potentials, nuclear level densities and -ray strength
functions, the nuclear uncertainties propagated through the
Hauser-Feshbach calculations are less than a factor of 2 which is well
below the average discrepancies of the calculated p-nuclei abundances
and the observations.
