R process nucleosynthesis
Thank you for the opportunity to help you with your question the solution is as such: the r-process is a nucleosynthesis process that occurs in core-collapse. During supernova nucleosynthesis, the r-process (r for rapid) creates very neutron-rich heavy isotopes, which decay after the event to the first stable isotope.
