高速带电粒子与核子的边缘电磁作用

本文研究了核子电磁结构对Weizs?cker-Williams等价光子谱理论的影响。为了克服Clementel-Villi型形式因子所导致的发散困难,提出了对这个形式因子的修改。计算的结果表明,在等价光子谱方法适用的范围内,碰撞的两个粒子,如果质量相差悬殊,主要还是W-W的结果。但在两粒子质量相近时,结构的影响就很明显。

THE PERIPHERAL ELECTROMAGNETIC INTERACTIONS OF THE FAST CHARGED PARTICLES AND NUCLEONS

In this paper, we have investigated the influence upon the modification of the theory of equivalent spectrum of photons by Weizs?cker-Williams, given by the electromagnetic structure of the nucleon. To overcome the difficulty caused by the divergence in the calculation with the form factor of the Clementel-Villi's type, we have suggested also a way of modifying the form factor.The results of the calculation show that within the region in which the method of equivalent spectrum of photons works, our results conform to Weizs?cker-Williams' theory, if the masses for the two particles in collision are considerably different; however, the influence of the structure is very evident, if the masses of the two particles are approximate to each other.
