Which neutron capture process occurs over a slower timescale, potentially requiring hundreds of thousands of years for a single capture event, and creates elements up to Bismuth?

Answer

The s-process (slow neutron capture)

The s-process involves slow neutron capture over extended timescales, capable of producing heavier isotopes up to elements like Bismuth.
