doubly magic number
解釋
雙幻數-
Since the magic number 28, which is the first that requires the introduction of a strong spin - orbit interaction belongs to the if2p shell in the nuclear shell model. so the nuclei in the if2p shell have been a research hotspot in nuclear physics. the doubly odd nucleus 64cu which is also in the if2p shell has been the subject of many experimental investigations previously via various type of nuclear reaction such as 64ni ( p, ny ) and its excitation leveles have been already studied to about 8 mev
放射性核素~ （ 64 ） cu是奇奇核，屬於1f 、 2p殼層，而在原子核殼模型中，第一個需要引入強自旋-軌道藕合才能出現的幻數就在1f 、 2p ? ?殼層，因此if 、 zp殼層一直是核物理領域的研究熱點，近三、四十年來使用了各種不同類型核反應例如『 4ni … ， fly ）等反應，對『 ll激發態性質進行了廣泛的研究，其激發能級已到了smev左右。
