a self-sustaining nuclear reaction; a series of nuclear fissions in which neutrons released by splitting one atom leads to the splitting of others
decay, disintegration, radioactive decay
the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation
endoergic reaction
a nuclear reaction occurring with absorption of energy
exoergic reaction
a nuclear reaction accompanied by the evolution of energy
fission, nuclear fission
a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy
fusion, nuclear fusion, nuclear fusion reaction

spallation
(physics) a nuclear reaction in which a bombarded nucleus breaks up into many particles
alpha decay
radioactive decay of an atomic nucleus that is accompanied by the emission of an alpha particle
beta decay
radioactive decay of an atomic nucleus that is accompanied by the emission of a beta particle
cold fusion
nuclear fusion at or near room temperatures; claims to have discovered it are generally considered to have been mistaken
thermonuclear reaction
a nuclear fusion reaction taking place at very high temperatures (as in the sun)
Type of:
