Stellar neutron capture reactions at low and high temperature

The determination of astrophysical reaction rates requires different approaches depending on the conditions in hydrostatic and explosive burning. focus here is for radiative neutron capture reactions. Relevant nucleosynthesis processes not only involve s-process but also i-, r- $\gamma$-processes, which from nuclear perspective mainly differ relative interaction energies neutrons nuclei, level densities involved nuclei. Emphasis put difference between reactions at low high temperature. Possible complications prediction measurement these are illustrated connection theory experiment addressed.
