Neutrino capture by r-process waiting-point nuclei
arXiv:nucl-th/9805007 · doi:10.1103/PhysRevC.58.2526
Abstract
We use the Quasiparticle Random Phase Approximation to include the effects of low-lying Gamow-Teller and first forbidden strength in neutrino capture by very neutron-rich nuclei with N = 50, 82, or 126. For electron neutrinos in what is currently considered the most likely r-process site the capture cross sections are two or more times previous estimates. We briefly discuss the reliability of our calculations and their implications for nucleosynthesis.
