Neutron capture on 130Sn during r-process freeze-out

We examine the role of neutron capture on Sn-130 during r-process freeze-out in the neutrino-driven wind environment of the core-collapse supernova. We find that the global r-process abundance pattern is sensitive to the magnitude of the neutron capture cross section of Sn-130. The changes to the abundance pattern include not only a relative decrease in the abundance of Sn-130 and an increase in the abundance of Sn-131, but also a shift in the distribution of material in the rare earth and third peak regions.
