论文摘要
用于研究原子核核结构的常见方法之一是核壳模型。与原子电子在轨道中的放置相似，在核壳模型中，质子和中子被认为填充了核内的轨道，按照保利的排除原则。这些轨道被分组在一起形成外壳，如果外壳中的所有可能的地方都已经满，则据说将其关闭。具有封闭壳的原子核非常稳定，比这些核更多的价核包括在核壳模型计算中。在这项研究中，使用核壳模型来研究通过将16o芯作为封闭的壳核来研究均匀的NE核的核结构。考虑到单个粒子轨道D5/2，S1/2和D3/2，并考虑了不同的参数集，用于价值之间的两体相互作用。将结果与当前的文献值进行比较。可以看出，使用USDB和SDNN的参数集获得了最接近实验值的结果。
One of the common methods used to investigate the nuclear structures of atomic nuclei is the nuclear shell model. Similar to the placement of atomic electrons into orbits, in the nuclear shell model, protons and neutrons are thought to fill the orbits within the nucleus, following the principle of Pauli's exclusion. These orbits are grouped together to form shells, which are said to be closed if all possible places in a shell are full. Atomic nuclei with closed shells are very stable and valence nucleons that are more than these nuclei are included in the nuclear shell model calculations. In this study, the nuclear shell model was used to investigate the nuclear structure of even-even Ne nuclei by considering the 16O core as a closed shell nuclei. Single particle orbits d5/2, s1/2 and d3/2 are taken into account and different parameter sets are used for two-body interactions between valance nucleons. The results were compared with each other and with current literature values. It was seen that the closest results to the experimental values were obtained with parameter sets of usdb and sdnn.
