Refining the r-process Described by Theoretical Models Research Advisor: Dr. Paul DeYoung Where did all of the heavy elements originate? The rapid neutron capture process (r-process), currently only characterized by theoretical calculations, model the nuclear reactions that lead to heavier nuclei in intense astrophysical locations such as supernovas. Experimenting with the few reactions reproducible on …

Grant to Nuclear Group Continues Three Decades of NSF Support

A new major research grant from the National Science Foundation (NSF) to the Nuclear Group at Hope College continues three decades of support from the agency, a long-time run which if not unique is at the very least rare, reflecting the quality of the work being conducted. Read more
