s-process

(slow neutron-capture process)
(synthesization of elements through neutron capture and beta decay)

The s-process (or slow neutron-capture process) is a nucleosynthesis process in stars consisting of neutron capture followed by beta decay, resulting in a nucleus with an mass number one more and an atomic number one more. Many of the elements heavier than iron result from this process. The word "slow" designates neutron capture at a sufficiently slow rate that a nucleus generally subsequently experiences beta decay before it captures yet another neutron.
