The rapid neutron-capture process, or so-called r-process, is a set of nuclear reactions that in nuclear astrophysics is responsible for the creation (nucleosynthesis) of approximately half the abundances of the atomic nuclei heavier than iron, usually synthesizing the entire abundance of the two most neutron-rich stable isotopes of.

The production of super-heavy transuranium elements by stellar nucleosynthesis processes remains an open question the most promising process that could potentially give rise to the formation of such elements is the so-called rapid neutron-capture process, or r-process, known to be at the origin of approximately half of the a 60 stable. Nuclear synthesis elements above iron perhaps in a matter of minutes, with the r-process because the intermediate products don't have time to decay.
