 Neutron capture nucleosynthesis

Neutron capture nucleosynthesis is a process in which atomic nuclei capture neutrons, leading to the formation of heavier elements. This process is primarily responsible for creating many of the elements in the universe that are heavier than iron. There are two main types of neutron capture processes: 1. **s-process (slow neutron capture process)**: This occurs in environments where neutrons are relatively scarce, such as in asymptotic giant branch (AGB) stars.
