论文摘要
在$^{41} $ ca和$^{41} $ CA和$^{35} $ SI ISOTONES之间的$ 2P_ {3/2} -2P_ {1/2} $中的中子旋转轨道拆分的减少$ 2p_ {35} $^{35} $ si Isotones之间是一个独特的功能。此外,它的减少方式,$^{41} $ ca和$^{35} $ si或$^{37} $ s和$^{35} $ si之间的突然及其起源,以及它的来源,是由$ p $状态或突然的中央质子密度depletion in $ p $ depletion在$ p $中造成的,是$^$^$ si^$ si^$ si {35}。此处使用DD-ME2参数化的自洽的协变量能量密度计算的结果指向$^{35} $ SI的局部减少,并指向中央密度耗竭效应的巨大优势。得出的结论是,必须考虑弱结合,中央密度耗竭以及相关性,以充分评估这种自旋轨道降低的幅度和原因。
The reduction of the neutron spin-orbit splitting $2p_{3/2} - 2p_{1/2}$ between the $^{41}$Ca and $^{35}$Si isotones is a unique feature throughout the chart of nuclides, as the spin-orbit splitting usually increases with $A$. Moreover, its way of decrease, gradual between $^{41}$Ca and $^{35}$Si or abrupt between $^{37}$S and $^{35}$Si, as well as its origin, caused by the weak binding energy of the $p$ states or by the sudden central proton density depletion in $^{35}$Si, are subject of debate. The results reported here using the self-consistent Covariant Energy Density Functional calculations with the DD-ME2 parametrization rather point to an abrupt, local decrease in $^{35}$Si, and to the large dominance of the central density depletion effect. It is concluded that weak binding, central density depletion as well as correlations must be taken into account to fully evaluate the amplitude and causes of this spin-orbit reduction.
