  Abundances of Mo isotopes predicted by stellar models of the s process are,
except for 95Mo, in good agreement with data from single grains of mainstream
presolar SiC. Because the meteorite data seemed sound and no reasonable
modification to stellar theory resulted in good agreement for 95Mo, it has been
suggested that the recommended neutron capture reaction rate for this nuclide
is 30% too low. Therefore, we have made a new determination of the
95Mo(n,gamma) reaction rate via high-resolution measurements of the
neutron-capture and total cross sections of 95Mo at the Oak Ridge Electron
Linear Accelerator. These data were analyzed with the R-matrix code SAMMY to
obtain parameters for resonances up to En = 10 keV. Also, a small change to our
capture apparatus allowed us to employ a new technique to vastly improve
resonance spin and parity assignments. These new resonance parameters, together
with our data in the unresolved range, were used to calculate the 95Mo(n,gamma)
reaction rate at s-process temperatures. We compare the currently recommended
rate to our new results and discuss their astrophysical impact.
