The magic numbers in exotic nuclei are discussed, and their novel origin is shown to be the spin-isospin dependent part of the nucleon-nucleon interaction in nuclei. The importance and robustness of this mechanism is shown in terms of meson exchange, G-matrix, and QCD theories. In neutron-rich exotic nuclei, magic numbers such as N = 8, 20, etc. can disappear, while N = 6, 16, etc. arise, affecting the structure of the lightest exotic nuclei to nucleosynthesis of heavy elements.
讨论了奇特原子核中的幻数，并表明它们的新奇起源是原子核中核子 - 核子相互作用的自旋 - 同位旋相关部分。从介子交换、G 矩阵和量子色动力学理论的角度展示了这种机制的重要性和稳健性。在富中子奇特原子核中，诸如 N = 8、20 等幻数可能消失，而 N = 6、16 等幻数出现，这影响了从最轻的奇特原子核到重元素核合成的结构。
