Missing Stark widths for 30 spectral lines of zinc ion (Zn IV) have been calculated using our quantum mechanical method. Recently, 21 Zn IV lines among the considered lines have been newly detected in the UV spectrum of the hot white dwarf G191B2B (DA type). This recent discovery encourages us to calculate their Stark widths to fill the lack of the data base STARK-B and for use in investigations of observed spectra in such stars. Before the Stark broadening evaluation, two steps of calculation have been carried out : in the first step, we calculate the atomic structure and then the electron-ion collision as a second step by the codes of University College London [SUPERSTRUCTURE (SST), DISTORTEDWAVE (DW), and JAJOM]. We provide our calculations for these lines at different temperature values and at density cm. We hope that the obtained results could be useful for the modelling of stellar atmospheres.

热白矮星大气中的 Zn IV 线宽 G191[公式省略]B2B：量子结果


使用我们的量子力学方法计算了 30 条锌离子 (Zn IV) 谱线的斯塔克缺失宽度。最近，在热白矮星G191B2B（DA型）的紫外光谱中新检测到了所考虑的谱线中的21条Zn IV谱线。最近的这一发现鼓励我们计算它们的斯塔克宽度，以填补 STARK-B 数据库的不足，并用于研究此类恒星的观测光谱。在斯塔克展宽评估之前，已经进行了两步计算：第一步，我们计算原子结构，然后计算电子-离子碰撞作为第二步，通过伦敦大学学院的代码[SUPERSTRUCTURE (SST), DISTORTEDWAVE （DW）和 JAJOM]。我们提供了这些线在不同温度值和密度 cm 下的计算结果。我们希望所获得的结果对于恒星大气的建模有用。
