格林函数蒙特卡罗方法中的电磁标度函数

Electromagnetic scaling functions within the Green's Function Monte Carlo approach

N. Rocco, L. Alvarez-Ruso, A. Lovato, J. Nieves

摘要:

本文研究了用格林函数蒙特卡罗方法计算的$^4$ He和$^{12}$ C核的电磁响应函数的标度性质。在相对论和非相对论情况下得到了纵向和横向标度函数,并与各种运动学的实验进行了比较。尽管模型具有非相对论性质,但在计算中出现了数据所显示的标度函数的特征非对称形状。结果与第零、第一类和第二类标度一致。我们的分析揭示了标度和核子密度响应函数之间的直接对应关系。

英文摘要:

We have studied the scaling properties of the electromagnetic response functions of $^4$He and $^{12}$C nuclei computed by the Green's Function Monte Carlo approach, retaining only the one-body current contribution. Longitudinal and transverse scaling functions have been obtained in the relativistic and non relativistic cases and compared to experiment for various kinematics. The characteristic asymmetric shape of the scaling function exhibited by data emerges in the calculations in spite of the non relativistic nature of the model. The results are consistent with scaling of zeroth, first and second kinds. Our analysis reveals a direct correspondence between the scaling and the nucleon-density response functions.
