摘要

我们的目标是为天体物理学、等离子体物理学、核聚变研究以及实验室和技术中的不同等离子体提供可靠的锡离子（Sn II）光谱线的斯塔克展宽数据。我们采用半经典扰动法计算了单电荷锡离子（Sn II）与电子和质子碰撞时 44 条光谱线的斯塔克展宽参数、半强度最大值全宽和位移。所得结果与现有的实验和理论结果进行了比较，并用于证明斯塔克展宽机制对恒星大气中锡离子（Sn II）光谱线的影响。

Stark broadening of Sn II spectral lines

Our objective is to provide reliable Stark broadening data for Sn II spectral lines needed for astrophysics, plasma physics, fusion research, and different plasmas in laboratory and technology. We used the semiclassical perturbation method for the calculation of Stark broadening parameters, full widths at half intensity maximum and shifts for 44 spectral lines of singly charged tin ion (Sn II), for collisions with electrons and protons. The obtained results have been compared with the existing experimental and theoretical results and used to demonstrate the influence of Stark broadening mechanism on spectral lines of Sn II in stellar atmospheres.
