Abstract

The energies and rates of Kα X-ray satellites due to 1s − 2p transitions in iodine and gold with one to multiple vacancies in the L shell are computed using Multi-Configuration Dirac Fock wavefunctions with the inclusion of relativistic and quantum electrodynamics corrections. The calculations have been carried out for I¹⁺ to I⁶⁺ with spectator vacancies in the 2p shell and Au¹⁺ to Au⁸⁺ with filled and empty 2s shell along with vacancies in the 2p shell. As existing data on the X-ray emission from low ionized iodine and gold are confined to single inner shell vacancy, direct comparison of the present results on the various radiative transitions from iodine and gold with a single vacancy in the K shell, variously ionized L shell and no vacancy in any other shells is possible only for the two well known Kα₁ and Kα₂ diagram lines. Hence to substantiate the reliability of the current results through one to one comparison with existing data on the 1s − 2p transitions, calculations have also been performed on the radiative decay of H-, He-, Be-, and F-like gold with singly ionized 1s, closed 2s, multiply ionized 2p and rest of the shells open for which semi-relativistic data exist. In addition to providing additional check on the reliability of the computed results, this comparison also tries to analyze the impact of higher order relativistic corrections on the K X-ray energies and rates. The intrinsic variations of transition properties with degree of ionization have been analyzed.

碘和金的K + X射线的多重电离L壳的能量和发射强度

摘要

K的能量和速率α透视卫星由于1个小号 - 2个p在碘转变和金之一的L壳的多个空缺使用多配置狄拉克Fock波一起列入相对论和量子电修正来计算。对于2 p外壳中具有观众空位的I ¹⁺至I ⁶⁺和2外壳中具有填充和空2 s外壳且空位为2 p的Au ¹⁺至Au ⁸⁺进行了计算贝壳。由于有关低离子化碘和金的X射线发射的现有数据仅限于单个内壳空位，因此直接比较了碘和金在K壳内具有单个空位的各种辐射跃迁的现有结果，即各种电离的L壳和在任何其他弹没有空位是可能只对两种熟知ķ α ₁和K α _2条图线。因此，为了通过与1 s  -2 p跃迁上的现有数据进行一对一比较来证实当前结果的可靠性，还对H-，He-，Be-和F类金的辐射衰减进行了计算。单电离1 s，关闭2 s，乘以2 p离子化，剩下的半壳打开，存在半相对论数据。除了对计算结果的可靠性进行额外检查外，该比较还试图分析高阶相对论校正对K X射线能量和速率的影响。分析了过渡性质随电离度的内在变化。
