论文摘要
使用壳模型的核结构研究中的主要成分之一是单粒子能量（SPE）。为了准确获得这些值，需要实验数据。在结构，反应和核天体物理学方面，双重魔术核素100SN周围的区域非常有趣。 101SN同位素的实验频谱数据是在该区域进行的核壳模型研究所必需的。由于文献中没有足够的实验数据，因此使用不同的方法用于该区域的SPE，例如在131SN中使用孔激发光谱或使用模型空间轨道轨道模型的最浅和最接近的同位素107SN。在这项工作中，我们在尚未实验确定的最高113SN和115SN的光同位素中进行了树单粒子状态S1/2，D3/2和H11/2的二阶多项式拟合。通过向光同位素推断，我们可以获得101SN中所有单粒子状态的激发能。随后，定义了模型空间轨道的中子SPE。使用新的相互作用进行了均匀的偶数和奇数102-107SN同位素的计算，并将结果与使用广泛使用的相互作用SN100PN获得的实验数据和结果进行了比较。
One of the main ingredients in nuclear structure studies using shell model are the single-particle energy (spe). In order to obtain these values accurately, experimental data is needed. The region around the doubly magic nuclide 100Sn is very interesting for nuclear studies in terms of structure, reaction and nuclear astrophysics. Experimental spectrum data for the 101Sn isotope is required for nuclear shell model studies to be carried out in this region. Since there is not enough experimental data in the literature, different approaches are used for the obtaining spes for the region such as using the hole excitation spectrum in 131Sn or using the lightest and closest isotope 107Sn which figures the model space orbitals. In this work, we have performed second order polynomial fits of the tree single-particle states s1/2, d3/2 and h11/2 in the light Sn isotopes up to 113Sn and 115Sn which are not determined yet experimentally. By an extrapolation toward light Sn isotopes, we can obtain the excitation energies of all the single-particle states in 101Sn. Subsequently, neutron spes of the model space orbitals are defined. Shell model calculations for even and odd 102-107Sn isotopes are carried out using the new interactions and the results are compared with the experimental data and results obtained using the widely used interaction sn100pn.
