介绍核力Yukawa势的一个简明推导

Introduction of a concise deduction to Yukawa-potentialof nuclear force

介绍J.M .Ziman书中的一个方法 。

Each nucleus gathered many nucleons (protons and neutrons),especially gathered many protons which are excluding each other but would not spread out.The cause just be the existence of an attractive force among nucleons--nuclear force.This force is aroused from the virtual partide exchange between two nucleons--virtual π meson exchange.This is the meson field theory for nuclear force.In the following,based on a reference listed in this paper,we deduced this picture and obtained the famous Yukawa potential of nuclear force.Although this theory is old,the picture possesses a general meanings because it is a general approach used to explain the originality of various interactions in the modern quantum field theory.
