摘要

用冲击半经典微扰理论计算了FeXXV3S2SJ-3P2POJ（cid:48）多重态谱线的斯塔克增宽参数、谱线宽度和谱线位移。所获得的结果已用于证明，尽管通常以˚A表示的线宽值差异很大，但当以角频率单位表示时，它们实际上是相同的。这证明，在Fe XXV谱线的情况下，我们可以使用以角频率单位表示的已知斯塔克增宽参数来获得相同多重态中其他谱线的未知参数。所获得的数据对中子星大气层、环境调查和建模以及惯性聚变等离子体特别有趣。

On the similarities of Stark broadening parameters within a Fe XXV multiplet

. Stark broadening parameters, line widths and shifts, have been calculated for spectral lines within Fe XXV 3s 2 S J -3p 2 P oJ (cid:48) multiplet, by using the impact semiclassical perturbation theory. The obtained results have been used to demonstrate, that in spite of big diﬀerences of line width values expressed as usual in ˚A, they are practically the same when expressed in angular frequency units. This conﬁrms that in the case of Fe XXV spectral lines we can use the known Stark broadening parameters, expressed in angular frequency units, to obtain the unknown ones, for other lines in the same multiplet. The obtained data are particularly interesting for neutron star atmospheres and environment investigation and modelling as well as for inertial fusion plasma.
