r-process - Wikipedia

In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set of nuclear reactions that is responsible for the creation of approximately half of the atomic nuclei heavier than iron; the "heavy elements", with the other half produced by the p-process and s-process.The r-process usually synthesizes the most neutron-rich stable isotopes of each heavy element.
