我们回顾了用于研究接近和超出中子和质子滴线的原子核的基态和激发态性质的各种理论模型。这些模型的有效性和局限性进行了讨论与应用程序，如双中子在Borromian核的相关性，软偶极激发，直接两个中子和两个质子衰变，和奇-偶交错的反应截面最近的实验结果。在质量A < 60的N = Z和N = Z + 2核的低能谱以及自旋和同位旋相关的衰变率中也指出了同位旋-三重态配对相互作用的作用。本文结合A = 11系统中T = 5/2倍数的同量异位素类似态（IAS）的能量，讨论了Borromian核11 Li的库仑能量位移的一个特征。
We review various theoretical models which have been used to study the properties of the ground state and excited states of nuclei close to and beyond the neutron and proton drip lines. The validity and limitations of these models are discussed with applications to recent experimental findings such as di-neutron correlations in Borromian nuclei, the soft dipole excitations, direct two-neutron and two-proton decays, and odd-even staggerings of reaction cross sections. The role of isoscalar spin-triplet pairing interaction is also pointed out in the low-lying energy spectra as well as the spin- and isospin-dependent decay rates for N = Z and N = Z + 2 nuclei with mass A < 60. A characteristic feature of the Coulomb energy displacement of the Borromian nucleus 11Li is discussed in connection to the energies of isobaric analogue states (IAS) of T = 5/2 multiples in the A = 11 systems.
