摘要

利用NushellX@MSU程序对44Ca、58Ni、62Ni和64Zn的核结构特性进行了弹性和非弹性形状因子的研究。这些核属于fp -壳区，并在模型空间中与GXPF1A和JUN45有效相互作用一起使用了Skyrme有效相互作用（Sk28, Sk35, Sk43）。44Ca的模型空间为（2p3/2, 1f7/2, 1f5/2, 2p1/2）， JUN45的模型空间为（2p3/2, 1f5/2, 2p1/2, 1g1 /2）。为了优化形状因子的计算，将Tassie模型应用于适当的质子和中子有效电荷，并考虑核极化（CP）效应。将计算的形状因子与实验数据和现有理论模型进行了比较。本研究提供了一个全面的分析CP对外形因素的影响，并证明了所使用的理论框架的可靠性。

Study of the nuclear structure of some FP-shell nuclei with Skyrme effective interaction

The nuclear structure properties, including elastic and inelastic form factors, were investigated for ⁴⁴Ca, ⁵⁸Ni, ⁶²Ni, and ⁶⁴Zn using shell model calculations with the NushellX@MSU code. These nuclei belong to the FP-shell region, and the Skyrme effective interaction (Sk28, Sk35, Sk43) was employed alongside the GXPF1A and JUN45 effective interactions in the model space. The model space for ⁴⁴Ca (2p3/2, 1f7/2, 1f5/2, 2p1/2), while JUN45 take the model space of (2p3/2, 1f5/2, 2p1/2, 1 g9/2). To refine the form factors calculations, the Tassie model was applied with appropriate proton and neutron effective charges, incorporating core-polarization (CP) effects. The calculated form factors were compared with experimental data and existing theoretical models. This study offers a comprehensive analysis of CP effects on form factors and demonstrates the reliability of the theoretical frameworks used.
