半满壳层原子中的束缚诱导轨道呼吸、聚变、fission和重排
Confinement induced orbital breathing, fusion, fission and re-ordering in semifilled shell atoms
摘要：
交替收缩和急剧膨胀，即，从理论上发现了电子子壳层的“呼吸”、两个子壳层熔合成一个子壳层及其随后裂变（分裂）成原始子壳层的效应，以及在约束逐渐变窄的半填充壳层原子中子壳层顺序的多次改变。禁闭由内半径为$r_{0}$的排斥可穿透球势表示。为了研究的完整性，通过门捷列夫表的第二、第三和第四行的受限半填充壳原子的计算数据来举例说明这些效应-分别具有半填充${2\rm s}^{1}$、${2\rm p}^{3}$、${3\rm p}^{3}$和${3\rm d}^{5}$子壳的Li、N、P和Cr原子。解释了所发现的效应背后的基本物理学。
英文摘要：
Alternate contraction and drastic expansion, i.e., `breathing' of electronic subshells, the effects of fusion of two subshells into one subshell and its subsequent fission (splitting) into the original subshells, as well as multiple alteration of the order of subshells in confined semifilled shell atoms with a progressively narrowing confinement are theoretically discovered. The confinement is represented by a repulsive penetrable spherical potential of an inner radius $r_{0}$. The effects are exemplified by calculated data for confined semifilled shell atoms from the second, third and fourth rows of Mendeleev's table - Li, N, P and Cr atoms with semifilled ${2\rm s}^{1}$, ${2\rm p}^{3}$, ${3\rm p}^{3}$ and ${3\rm d}^{5}$ subshells, respectively - for the completeness of the study. The underlying physics behind the discovered effects is explained.
