模拟镍K线的辐射和俄歇衰变数据
Radiative and Auger decay data for modelling nickel K lines
摘要:
辐射和俄歇衰变数据已被计算用于模拟的镍离子的issues序列的K线,从Ni $^+$到Ni $^{27+}$。能级能量,过渡波长,辐射跃迁几率,辐射和俄歇宽度已被确定使用Cowan的Hartree-Fock与相对论修正(HFR)方法。俄歇宽度的第三行离子(镍$^+$ -镍$^{10+}$)已被计算使用单组态平均(SCA)紧凑的公式。结果进行了比较与AUTOSTRUCTURE和MCDF原子结构代码计算的数据集,并与现有的实验和理论值,主要是在高度电离的离子和固体状态。
英文摘要:
Radiative and Auger decay data have been calculated for modelling the K lines in ions of the nickel isonuclear sequence, from Ni$^+$ up to Ni$^{27+}$. Level energies, transition wavelengths, radiative transition probabilities, and radiative and Auger widths have been determined using Cowan's Hartree--Fock with Relativistic corrections (HFR) method. Auger widths for the third-row ions (Ni$^+$--Ni$^{10+}$) have been computed using single-configuration average (SCA) compact formulae. Results are compared with data sets computed with the AUTOSTRUCTURE and MCDF atomic structure codes and with available experimental and theoretical values, mainly in highly ionized ions and in the solid state.
