Post Event Neutron Exposure of r-Process Material,
Abstract
The effects of neutron fluxes on r-process material following the r-process event are considered. The calculations examine the case of neutron exposure occurring after the r-process material has decayed back to or near the valley of beta stability. Such exposure may occur during the r-process freeze-out or in some other subsequent neturon exposure. Limitations on these neutron fluxes are inferred from odd-even effects in the A about 130 and A about 195 r-process peaks and from the abundances of certain s-only nuclei. The effects of these neutron fluxes on the abundances of lead, bismuth and the nucleochronologically important actinides are examined. (Author)
