What mechanism is required to create elements heavier than iron during a supernova explosion?

Rapid neutron capture (the *r*-process)

The immense energy and flood of neutrons released during the supernova explosion enable the rapid neutron capture process, creating elements far heavier than iron, such as gold and uranium.
