The relatively rapid nucleosynthesis process, in supernovae, in which a large neutron flux allows rapid neutron capture and synthesis of elements up to the transuranic elements.
The r-process is a nucleosynthesis process, that occurs in core-collapse supernovae, and is responsible for the creation of approximately half of the neutron-rich atomic nuclei heavier than iron. The process entails a succession of rapid neutron captures by heavy seed nuclei, typically 56Fe or other more neutron-rich heavy isotopes. The other predominant mechanism for the production of heavy elements is the s-process, which is nucleosynthesis by means of slow captures of neutrons, primarily occurring in AGB stars. The s-process is secondary, meaning that it requires preexisting heavy isotopes as seed nuclei to be converted into other heavy nuclei. Taken together these two processes account for a majority of galactic chemical evolution of elements heavier than iron. The r-process occurs to a slight extent in nuclear weapon explosions.
