We present results of measurements of the oscillator strength of intercombination lines of He-like Vanadium ions in high energy density (HED) laser-produced-plasmas and compare them with the simulations from commonly used codes and data from the NIST database. Whilst not yet sufficiently accurate to constrain different trusted atomic-physics models for the particular system studied, our results are in agreement with the available data within experimental error bars, yet differ from cruder approximations of the oscillator strength used in certain atomic-kinetics packages, suggesting that this general method could be further extended to be used as a measurement of the oscillator strength of additional atomic transitions under the extreme conditions that are achieved in HED experiments.

我们介绍了在高能量密度（HED）激光产生的等离子体中类似He的钒离子的复合线的振荡器强度的测量结果，并将其与常用代码和NIST数据库数据的模拟进行了比较。尽管还不够准确，无法针对所研究的特定系统约束不同的可信任原子物理学模型，但我们的结果与实验误差条内的可用数据相符，但与某些原子动力学软件包中使用的振荡器强度的粗略估计有所不同，这表明该通用方法可以进一步扩展，以用作在HED实验中达到的极端条件下其他原子跃迁的振荡器强度的测量。
