Which process is responsible for creating roughly half of the elements heavier than iron, such as bismuth?

Answer

The s-process (slow neutron capture)

The s-process occurs in aging asymptotic giant branch (AGB) stars, where nuclei slowly capture neutrons, allowing unstable isotopes time to decay into the next stable element.
