摘要

用时间分辨激光诱导荧光法测量了Tb III在52,039 ~ 62,734 cm−1能量范围内的19个奇宇称能级的自然辐射寿命。据我们所知，19个级别中有16个的寿命是首次测量。采用伪相对论Hartree-Fock方法计算了所研究能级的寿命和分支分数（BFs）。结合实测寿命和理论BFs，确定了245个谱线的半经验跃迁概率和振子强度，其中58个谱线是首次确定的。

Experimental and theoretical radiative parameters of some odd-parity levels in Tb III

Natural radiative lifetimes of 19 odd-parity levels of Tb III in the energy range between 52,039 and 62,734 cm⁻¹ were measured by the time-resolved laser-induced fluorescence method. To our knowledge, the lifetimes for 16 out of 19 levels were measured for the first time. The pseudo-relativistic Hartree-Fock method was used to calculate the lifetimes and branching fractions (BFs) of the investigated energy levels. Combining the measured lifetimes with the theoretical BFs, the semiempirical transition probabilities and oscillator strengths for 245 lines were determined, 58 lines of which were determined for the first time.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
