the rule that near threshold a reaction or scattering cross section varies as a power of energy fixed by the angular momentum of the outgoing partial wave.

In atomic, molecular and optical physics, Wigner threshold law refers to the rule that near threshold a reaction or scattering cross section varies as a power of energy fixed by the angular momentum of the outgoing partial wave. This meaning comes from Wigner (1948) in Physical Review.[1]
