Query: Photoneutron reaction cross section measurements on 94Mo and 90Zr
  relevant to the p-process nucleosynthesis   The photodisintegration cross sections for the 94Mo({\gamma},n) and
90Zr({\gamma},n) reactions have been experimentally investigated with
quasi-monochromatic photon beams at the High Intensity {\gamma}-ray Source
(HI{\gamma}S) facility of the Triangle Universities Nuclear Laboratory (TUNL).
The energy dependence of the photoneutron reaction cross sections was measured
with high precision from the respective neutron emission thresholds up to 13.5
MeV. These measurements contribute to a broader investigation of nuclear
reactions relevant to the understanding of the p-process nucleosynthesis. The
results are compared with the predictions of Hauser-Feshbach statistical model
calculations using two different models for the dipole {\gamma}-ray strength
function. The resulting 94Mo({\gamma},n) and 90Zr({\gamma},n) photoneutron
stellar reaction rates as a function of temperature in the typical range of
interest for the p-process nucleosynthesis show how sensitive the photoneutron
stellar reaction rate can be to the experimental data in the vicinity of the
neutron threshold.
