Yukawa potential

[yü′kä·wä pə‚ten·chəl]
(nuclear physics)
The potential function that is associated with the Yukawa force, with the form V (r) = -V0(b/r) exp (-r/b), where r is the distance between the nucleons and V0 and b are constants, giving measures of the strength and range of the force respectively.

In retrospect, the same procedure which has been traditionally used to derive the Yukawa potential, by using radial biquaternion Klein-Gordon potential, yields a PT-symmetric periodic potential which takes the form of equation (1).
Yukawa Potential. Setting [V.sub.0] = B = C = 0 in (1) then the potential reduced to Yukawa potential.
In the present article we presented here for the first time a numerical/computer solution of radial biquaternionic KGE (radialBQKGE); which differs appreciably from conventional Yukawa potential.
