9317828 Beck Research will focus on the theoretical calculation of the properties of lanthanide and actinide atoms and negative ions. The lanthanides are beginning to be studied experimentally using accelerator mass spectrometry and little is known about the electron affinities of the negative ions. Many body and relativisitic effects will be included in order to obtain reliable results. The relativistic configuration interaction method developed under the previous grant is now sufficiently mature to undertake the challenge of this complicated atomic species. ***

小行星9317828 研究重点是镧系元素和锕系元素原子以及负离子性质的理论计算。 镧系元素开始使用加速器质谱法进行实验研究，对负离子的电子亲和势知之甚少。 为了获得可靠的结果，许多体效应和相对论效应将被包括在内。 相对论组态相互作用的方法下开发的前一个赠款，现在已经足够成熟，承担这一复杂的原子物种的挑战。 ***
