我们报告了一个偏振测量的壳层辐射复合（RR）x射线发射的He到F-类铋离子。的极化功能，从康普顿散射RR X射线的方位角分布，最近开发的国家的最先进的康普顿偏振仪安装在电子束离子阱检测。这是有史以来进行的极少数RR x射线偏振测量之一，也是第一次使用铋离子。我们推导出在电荷态上平均的线极化度为。相比之下，用灵活原子码（fac）对偏振度的理论估计产生。观测值和理论值之间的差异可能是由于电子相关效应。
We report a polarization measurement of-shell radiative recombination (RR) x rays emitted from He- to F-like bismuth ions. The polarization feature was obtained from the azimuthal angular distribution of the Compton-scattered RR x rays detected with a recently developed state-of-the-art Compton polarimeter installed on an electron beam ion trap. This is one of a very few polarization measurements of RR x rays ever conducted and the first one with bismuth ions. We derived the degree of linear polarization averaged over the charge states to be. By contrast, a theoretical estimation of the degree of polarization with the Flexible Atomic Code (fac) yields. The discrepancy between the observed and theoretical values is likely to be due to the electron correlation effects.
