weak interaction
n.
A fundamental interaction between elementary particles that is several orders of magnitude weaker than the electromagnetic interaction and is responsible for some particle decay, nuclear beta decay, and neutrino absorption and emission. Also called weak force.

weak interaction, force
n
(Physics / General Physics) Physics an interaction between elementary particles that is responsible for certain decay processes, operates at distances less than about 10-15 metres, and is 1012 times weaker than the strong interaction. The weak interaction and electromagnetic interactions are now described by the unifying electroweak theory Also called weak nuclear interaction, force See interaction [2] electroweak interaction
