内原子的壳层间关联

Intershell correlations in endohedral atoms

M. Ya. Amusia, L. V. Chernysheva

摘要:

我们已经计算了不同的内和原子的子壳的总偶极和规则的框架中的无规相位近似与交换(RPAE)的部分贡献,并发现它们是本质上不同的电子在各自的子壳的数量。这种差异表明壳层间相互作用的强度。我们提出了具体的计算结果的多面体,组成的富勒烯C60和所有的稀有气体He,Ne,Ar,Kr和naturthus分别形成He@C60,Ne@C60,Ar@C60,Kr@C60,和Xe@C60。为了比较,我们对孤立的惰性气体原子也得到了类似的结果。偏离电子数在外部subshells被证明是更大的比在孤立的原子,从而表现出相当强的壳层间的相关性。

英文摘要:

We have calculated partial contributions of different endohedral and atomic subshells to the total dipole sum rule in the frame of the random phase approximation with exchange (RPAE) and found that they are essentially different from the numbers of electrons in respective subshells. This difference manifests the strength of the intershell interaction. We present concrete results of calculations for endohedrals, composed of fullerene C60 and all noble gases He, Ne, Ar, Kr and Xe thus forming respectively He@C60, Ne@C60, Ar@C60, Kr@C60, and Xe@C60. For comparison we obtained similar results for isolated noble gas atoms. The deviation from number of electrons in outer subshells proved to be much bigger in endohedrals than in isolated atoms thus demonstrating considerably stronger intershell correlations there.
