Abstract We present excitation energies, emitted photon wavelength during the transition from upper level to lower level, lifetimes, transitions rates and other transition parameters for first fine structure 200 levels of W LXVII and W XLIX by using Multi-Configuration Dirac-Fock (MCDF) scheme in our calculations. We endorse that contributions of relativistic effects QED and Breit corrections in energies of levels are significant. We have also shown that our results of energies from both, Flexible Atomic Code (FAC) and General Purpose Atomic Structure Package (GRASP) matches with each other and also with NIST and other experimentally measured and theoretically calculated results. We have predicted all soft x-ray (SXR), hard x-ray (HXR), extreme ultraviolet (EUV) and far UV transitions from ground state in W LXVII and W XLIX. Furthermore, we have also provided relative population for first five excited states, partition function and thermodynamic quantities for both W LXVII and W XLIX and studied their variations with temperature. Besides, detailed new atomic data and thermodynamic data of W LXVII and W XLIX which are not published so far in the literature have been reported and can be advantageous in the field of modelling of fusion and astrophysical plasmas, cell biology and microscopic imaging.

W LXVII 和 W XLIX 的激发能量、SXR、HXR、EUV 和远紫外光谱线的跃迁数据以及配分函数、热力学参数和能级布居

摘要 我们使用多配置狄拉克-福克 (MCDF) 展示了 W LXVII 和 W XLIX 的第一精细结构 200 能级的激发能量、从高能级到低能级跃迁期间发射的光子波长、寿命、跃迁率和其他跃迁参数在我们的计算方案。我们赞同相对论效应 QED 和 Breit 修正对能级能量的贡献是显着的。我们还表明，来自灵活原子代码 (FAC) 和通用原子结构包 (GRASP) 的能量结果彼此匹配，并且与 NIST 和其他实验测量和理论计算结果相匹配。我们已经预测了 W LXVII 和 W XLIX 中所有从基态的软 X 射线 (SXR)、硬 X 射线 (HXR)、极紫外 (EUV) 和远紫外跃迁。此外，我们还提供了 W LXVII 和 W XLIX 的前五个激发态、分配函数和热力学量的相对种群，并研究了它们随温度的变化。此外，W LXVII 和 W XLIX 的详细新原子数据和热力学数据尚未在文献中发表，在聚变和天体物理等离子体建模、细胞生物学和显微成像领域具有优势。
