R Process Nucleosynthesis In Supernovae
r-process — WikipediaThe rapid neutron capture process or r-process is a set of reactions in nuclear astrophysics that are responsible for the creation (nucleosynthesis) of approximately half the atomic nuclei heavier than iron. These include the material ejected from a core-collapse supernova (as part of supernova nucleosynthesis) and Supernova nucleosynthesis — WikipediaDuring supernova nucleosynthesis, the r-process (r for rapid) creates very neutron-rich heavy isotopes, which R-Process Nucleosynthesis in Supernovae — UMd…R-Process Nucleosynthesis in Supernovae.
