我们提出了一种从原子核的包容结构函数中提取中子结构函数的新方法，该方法采用求解积分卷积方程的迭代过程。与早期的方法不同，新方法适用于自旋平均和自旋相关的结构函数。我们测试了该方法在核子共振和深非弹性区域中氘核的非极化 F{sub 2} 和极化 g{sub 1} 结构函数上的可靠性。新方法只需几次迭代就能以非常好的精度再现几乎任意形状的已知输入函数。
We propose a new method for extracting neutron structure functions from inclusive structure functions of nuclei, which employs an iterative procedure of solving integral convolution equations. Unlike earlier approaches, the new method is applicable to both spin-averaged and spin-dependent structure functions. We test the reliability of the method on unpolarized F{sub 2} and polarized g{sub 1} structure functions of the deuteron in both the nucleon resonance and deep inelastic regions. The new method is able to reproduce known input functions of almost arbitrary shape to very good accuracy with only several iterations.
