Neutron capture

Neutron capture is a nuclear reaction in which an atomic nucleus and one or more neutrons collide and merge to form a heavier nucleus. Since neutrons have no electric charge, they can enter a nucleus more easily than positively charged protons, which are repelled electrostatically. Neutron capture plays a significant role in the cosmic nucleosynthesis of heavy elements. In stars it can proceed in two ways: as a rapid process (r-process) or a slow process (s-process). Nuclei of masses greater than 56 cannot be formed by thermonuclear reactions (i.e., by nuclear fusion) but can be formed by neutron capture.Neutron capture on protons yields a line at 2.223 MeV predicted and commonly observed in solar flares. (Wikipedia).

Teach Astronomy - Fission as an Energy Source

http://www.teachastronomy.com/ Fission is such an efficient energy source that humans have long tried to harness it. A massive atomic nucleus can be split by a neutron. Since the decay of a massive nucleus can also release a neutron, this raises the possibility of a chain reaction where
