Yukawan.

/jʊˈkɑːwə/

Etymology: < the name of Hideki Yukawa (1907–81), Japanese physicist.

Nuclear Physics.

Used attributively with reference to the theory of the strong interaction between nucleons put forward by Yukawa, in which it is mediated by the exchange of particles ( Yukawa particles) subsequently identified with pions; Yukawa potential n. a potential function of the form V = V₀(r/r₀)⁻¹ exp(−r/r₀), occurring in Yukawa's theory of the nuclear force.
