利用相对论Hartree-Fock(RHF)理论中的单粒子能谱,用Strutinsky方法提取壳层修正能。发现在求解RHF方程时,选择合适的盒子尺寸对提取可靠的Strutinsky壳层修正能是很重要的。通过对各种核图上的原子核的系统研究,包括轻核、重核、缺中子核和富中子核,提出了一个确定的经验公式。此外,还计算了Ca、Pb和Og同位素的壳层修正能,并讨论了由于不确定性引起的不确定性。结果表明,Strutinsky方法提取的核壳层结构信息是可靠的,可用于构建宏观-微观质量模型.
The single-particle spectra in relativistic Hartree-Fock (RHF) theory are employed to extract shell correction energies with the Strutinsky method. It is found that proper box sizesused in solving the RHF equations are important to extract reliable Strutinsky shell correction energies. An empirical formula to determineis proposed by systematic studies on nuclei over a wide range of nuclear charts, including light, heavy, neutron-deficient, and neutron-rich nuclei. Furthermore, the shell correction energies of Ca, Pb, and Og isotopes andisotones are calculated with properand their uncertainties due to the uncertainty ofare investigated as well. It is found that the results extracted by the Strutinsky method provide a reliable evaluation of the nuclear shell structure information, which can be employed to construct a macroscopic-microscopic mass model in the future.
