Description
Neutron-capture cross sections play a vital role in our understanding of heavy element nucleosynthesis and applications relevant to nuclear security. Reaction networks in these regions involve short-lived isotopes for which capture cross sections cannot be measured via direct techniques. Instead reactions in these regions rely on calculations that can have uncertainties up to a few orders of magnitude. The Kr-Sr region is of particular importance for astrophysical processes and applications. In this presentation, I will discuss experimental (d,p$\gamma$) studies on the Kr and Sr isotopes at the TRIUMF Facility using the TIGRESS and SHARC arrays, and how measured particle-gamma coincidences can be used to provide experimental constraints for capture cross sections on short-lived nuclei using multiple techniques.
