摘要

计算了12C和20Ne原子核在基态和激发态的弹性和非弹性电子核散射的库仑形状因子。我们使用了一种微观理论,涉及模型空间外高配置的影响,称为核心极化(CP)效应。对于核心极化矩阵元素,使用三程Yukawa(M3Y)相互作用和改进的表面-德尔塔相互作用(MSDI)的真实密歇根和作为两体相互作用。此外,谐波振荡器(HO)电势被应用于计算波函数。在最后一步中,对基于(M3Y)和(MSDI)相互作用的库仑形状因子的理论计算与可用的实验数据进行了比较。值得注意的是,(M3Y)相互作用的库仑形状因子给出了测量数据的合理描述。

Comparison between the Theoretical Calculation of Coulomb Form Factors and Experimental Data for 12C and 20Ne Nuclei
The Coulomb form factors for the elastic and inelastic electron-nucleus scatterings have been calculated for 12C and 20Ne nuclei in the ground and excited states with the same parity. We use a microscopic theory involving the effects from high configurations outside the model space, which are called the Core Polarization (CP) effects. For the core polarization matrix elements, the realistic Michigan sum of the three-range Yukawa (M3Y) interaction and the Modified Surface Delta Interaction (MSDI) are used as the two-body interactions. Additionally, the Harmonic Oscillators (HO) potential is applied to calculate wave functions. In the final step, a comparison has been made between the theoretical calculations of Coulomb form factors based on (M3Y) and (MSDI) interactions and the available experimental data. It is noticed that the Coulomb form factors for the (M3Y) interaction give a sensible delineation of the measured data.
