1. Note that this potential has the same form as the Yukawa potential . 2. However, any Yukawa potential or Coulomb potential are non-zero for any large r. 3. The Yukawa potential ( also called a screened Coulomb potential ) is a potential of the form 4. Yukawa potential or some variant thereof.5. In the SI system, the unit of the Yukawa potential is ( 1 / m ). 6. Regge trajectories can be obtained for many other potentials, in particular also for the Yukawa potential . 7. This theoretical development included a description of the Yukawa potential , an early example of a nuclear potential. 8. It can be seen that the Coulomb potential has effect over a greater distance whereas the Yukawa potential approaches zero rather quickly. 9. The Yukawa potential depends only on the distance between particles, " r ", hence it models a central force. 10. The decrease is approximately as a negative exponential power of distance, though there is no simple expression known for this; see Yukawa potential .
