论文摘要
通过相对论的Hartree-Bogoliubov(RHB)方法研究了从Z = 32到Z = 38的异国情调均匀的链,并使用显式密度依赖性依赖性的MESON-EXCHANGE(DD-ME2)和密度依赖性点耦合(DD-PC1)模型(DD-PC1)模型。经典的魔术数n = 50被复制,新数字n = 70被预测是通过分析几个计算的数量,例如:两中性分离能,两中性壳体壳体间隙,中子配对能,势能表面和具有张力力的单个粒子能量。获得的结果通过壳模型计算证实,并将其与有限范围液滴模型(FRDM)的预测以及可用的实验数据进行了比较。建立了理论模型和实验之间的合理且令人满意的一致性。
The exotic even-even isotopic chains from Z=32 to Z=38 are investigated by means of the relativistic Hartree-Bogoliubov (RHB) approach with the explicit Density Dependent Meson-Exchange (DD-ME2) and Density Dependent Point-Coupling (DD-PC1) models. The classic magic number N=50 is reproduced and the new number N=70 is predicted to be a robust shell closure by analysing several calculated quantities such as: two-neutron separation energies, two-neutron shell gap, neutron pairing energy, potential energy surface and neutron single particle energies with and without the tensor force. The obtained results are corroborated by shell model calculations and compared with the predictions of finite range droplet model (FRDM) and with the available experimental data. A reasonable and satisfactory agreement between the theoretical models and experiment is established.
