摘要:

本文用相对论耦合团簇方法精确计算了重要的电磁跃迁振幅及其多体关联。超精细相互作用常数的研究,对等离子体诊断有用,与此相关详尽的多体方法是这项工作的另一个重要领域。计算的振子强度的允许跃迁,禁戒跃迁的振幅和寿命进行了比较,与其他理论结果在任何地方,他们表现出良好的协议。本文给出的WVI各同位素的超精细常数,将有助于获得该元素在不同天体中丰度的精确图象。

英文摘要:

This work presents precise calculations of important electromagnetic transition amplitudes along with detail of their many-body correlations using relativistic coupled cluster method. Studies of hyperfine interaction constants, useful for plasma diagnostic, with this correlation exhaustive many-body approach are another important area of this work. The calculated oscillator strengths of allowed transitions, amplitudes of forbidden transitions and lifetimes are compared with the other theoretical results wherever available and they show a good agreement. Hyperfine constants of different isotopes of W VI, presented in this paper will be helpful to get accurate picture of abundances of this element in different astronomical bodies.
