Description

We study the sensitivity of the r-process nucleosynthesis to the nuclear reactions of light nuclei.
We first update nuclear reaction data in Libnucnet code if available in experiments. We then calculate the r-process nucleosynthesis in the core-collapse supernovae and collapsar. For core-collapse supernovae we consider two different scenarios: the magnetohydrodynamic (MHD) jet model and a simple exponential model for the weak r-process.
We find important reactions such as 14C(n, gamma)15C to which the r-process is sensitive. We finally discuss reaction network flows under the various conditions.
