摘要:

我们用冷靶反冲离子动量谱(COLTRIMS)研究了Ne分子$_2$在K壳层光电离后的衰变。分裂成Ne $^{1+}$ / Ne $^{2+}$表明在前一个原子俄歇衰变之后发生原子间库仑衰变(ICD)。的光电子和ICD电子的分子框架角分布显示出不同的,不对称的功能,这意味着本地化的K-空位创建的两个原子的网站之一的Ne $_2$和ICD电子从本地化网站的发射。实验结果得到了冻芯Hartree-Fock方法计算结果的支持。

英文摘要:

We used Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) to investigate the decay of Ne$_2$ after K-shell photoionization. The breakup into Ne$^{1+}$ / Ne$^{2+}$ shows interatomic Coulombic decay (ICD) occurring after a preceding atomic Auger decay. The molecular frame angular distributions of the photoelectron and the ICD electron show distinct, asymmetric features, which imply localization of the K-vacancy created at one of the two atomic sites of the Ne$_2$ and an emission of the ICD electron from a localized site. The experimental results are supported by calculations in frozen core Hartree-Fock approach.
