| 摘 要： | 本文根据Sugawara和Kanazawa所证明的一个定理和Omnes关于渐近行为的研究,讨论了Gi(t)和Гi(t)色散关系的減出问题。比较仔细地考虑了Гi(t)和Fπ(t)中远区奇异性的贡献,所得的结果可以同时很好地符合电形式因子和磁形式因子。其中Гi(t)并满足Vick从πN实验分析中所提出的要求。计算结果还表明,核子的矢量总电荷和总磁矩绝大部分是由2π中间态贡献的,核子的核心点电荷和点磁矩

| Abstract: | In reference to a theorem proved by Sugawara and Kanazawa together with recent studies of asymptotic behaviour by Omnes, the subtration in the dispersion relations of Gi(t) and Гi(t) is discussed. The contributions to the Гi(t) and Fπ(t) by the "far away" singularities are accounted for more carefully; the results so obtained seem to agree pretty well with both the electric and magnetic isotopic vector form factors; the Гi(t) satisfies the requirement proposed by Vick from the analysis of π-N scattering data. Our calculation also shows that the total isotopic vector charge and magnetic moment are mainly due to the 2π intermediate state contribution; it is very probable that there exist no core point charge and magnetic moment at all. |
