1. (abbr.) Light Neutron Blasters and variations. 2. (abbr.) Heavy Neutron Blasters and variations. 3. (abbr.) Neutron Blaster Cannons and variations.
Electrically neutral elementary particles found in all atomic nuclei except light hydrogen; the mass is equal to that of the proton and electron combined and they are unstable when isolated from the nucleus, undergoing beta decay. Slow, thermal, epithermal, and fast neutrons refer to the energy levels with which the neutrons are ejected from heavie...
