Free neutron decay

A free neutron refers to a neutron that is not bound to an atomic nucleus. When embedded in a stable nuclide, neutrons have not been observed to decay. Free neutrons decay with a mean lifetime of 878.4±0.5 s (nearly 15 minutes), which corresponds with a half-life of around 608 seconds.
