论文摘要
在这项工作中,我们在质子和中子中确定了中央密度耗竭的独特而新颖的特征,称为50 $ \ leq $ z(n)$ \ leq $ 82区域中的偶然气泡核。探测了2d-3s单粒子(S.P.)状态在Halo和Bubble Nuclei存在中的主要作用。 S.P.的占用状态3s $ _ {1/2} $导致扩展中子密度分布或光晕,而净收入会导致中心密度耗竭。通过采用相对论平均场(RMF)进近以及NL3*参数,分离能,单粒子能,配对能,质子和中子密度谱以及均匀的核的变形。我们的结果与其他理论和可用的实验数据简洁明了。在这个未知的地区,系统地探索了新的外壳封闭和传统外壳封闭的魔力。
In this work, we identify a unique and novel feature of central density depletion in both proton and neutron named as doubly bubble nuclei in 50$\leq$Z(N)$\leq$82 region. The major role of 2d-3s single-particle (s.p.) states in the existence of halo and bubble nuclei is probed. The occupancy in s.p. state 3s$_{1/2}$ leads to the extended neutron density distribution or halo while the unoccupancy results in the central density depletion. By employing the Relativistic Mean-Field (RMF) approach along with NL3* parameter, the separation energies, single-particle energies, pairing energies, proton, and neutron density profiles along with deformations of even-even nuclei are investigated. Our results are in concise with few other theories and available experimental data. Emergence on new shell closure and the magicity of conventional shell closures are explored systematically in this yet unknown region.
