R-process
The
r-process
is a
nucleosynthesis
process that occurs in core-collapse
supernovae
(see also
supernova nucleosynthesis
) 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
(hence the name r-process) by heavy
seed nuclei
, typically
56
Fe or other more neutron-rich heavy isotopes.
