论文摘要
对于诸如Nucleon之类的系统，其固有大小的核心尺寸均在其Compton波长阶的情况下，本地运算符的矩阵元素与相关外形的傅立叶变换之间的关系失败。尽管可以构想质子中固有的电荷密度分布，但似乎没有一种明确的方式来确切定义，计算或测量它。
The relationship between the matrix element of a local operator and the Fourier transform of the associated form factor fails for systems such as the nucleon where its intrinsic size is of order its Compton wavelength. Although one can conceive of an intrinsic charge density distribution in the proton, there does not seem to be an unambiguous way to define, compute, or measure it precisely.
