In the chapter four , we studied some low - lying absorption spectroscopy and the resonant absorption probability of bohrium ( z = 107 ) by using mcdf method which included the correlation effects and relativistic effects systematically . we got some satisfied results of the ionization energy which make a good agreement with the results obtained by the semi - empirical method 论文第四章通过系统考虑电子相关效应和相对论效应，使用mcdf方法进一步预言了107号元素bh的几个较低的激发态能级以及由基态到这些激发态的共振吸收率，得到的电离能和使用半经验方法得到的电离能结果具有很好的一致性。

Using the multi - configuration dirac - fock method ( mcdf ) , we studied the characteristic of the decay processes of the 4d core excited states of csiv , the low - lying excitation structure of super - heavy element bohrium ( z = 107 ) and the x - ray spectra of the 3d - 4f transitions of highly charged xenon ions in details in this work , by including the electron correlation and the relaxation effects systematically 本论文运用mcdf方法，通过系统考虑电子相关效应和驰豫效应，分别研究了cs离子的4d内壳层激发态衰变动力学特性，超重元素bh ( z = 107 )的低激发态结构以及高离化态氙离子的3d - 4f跃迁产生的x射线谱的结构等问题。
