Deuteron Form Factor A(Q2) in the Paris Potential Wave Function

Keywords： electromagnetic form factor of deuteron , Paris potential wave function , elastic electron scattering on deuteron

在非相对论的框架内和应用描述了高动量过程的巴黎势所产生的氘核的波函数，计算了氘核的电磁形状因子A(Q2)。A(Q2)因子化为氘核的结构凾数Z(t)和偶极形状GD(t)之积。结构函数Z(t)是用巴黎势的波函数做数值计算而得到的。对A(Q2)的预言跟实验数据的分析非常一致，这一对实验结果的成功描述说明：氘核形状因子A(Q2)这一简单的理论描述是非常成功的，并且可以用到氘核的其他静态性质的研究。

Within non-relativistic framework and using deuteron wave function produced by the Paris potential which is designed just for describing nuclear process at high momentum transfers, we calculate deuteron electromagnetic form factor A(Q2) which is formulized as a product of the deuteron structure function Z(t) and dipole form factor GD(t). The structure function Z(t) is obtained numerically from the Paris potential wave function calculations. Our theoretical prediction for A(Q2) is in a good agree-ment with experimental data available. This successful fit to data shows that the simple theoretical description of deuteron form factors A(Q2) works quite well, and could be applied to studying other static properties of deuteron.
