Abstract

β-delayed neutron emission branchings (or upper limits) for neutron rich Rh116-120, Pd120-122, and Ag124 have been measured. These branching ratios serve as direct inputs to astrophysical rapid neutron capture process models and affect the final abundances calculated in these models. In addition, half-lives for neutron rich Tc114-115, Ru114-118, Rh116-121, and Pd119-124 near the proposed path of the r-process have also been measured. The results agree with theoretical quasiparticle random-phase approximation calculations within model uncertainties; the only exception is the delayed neutron branching in the decay of Rh120, which is found to be much smaller than predicted.
