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.

Sn II 谱线的明显展宽


我们的目标是为天体物理学、等离子体物理学、聚变研究以及实验室和技术中的不同等离子体所需的 Sn II 谱线提供可靠的 Stark 展宽数据。我们使用半经典扰动方法来计算 Stark 展宽参数、最大强度半的全宽以及与电子和质子碰撞的 44 条单电荷锡离子 （Sn II） 谱线的偏移。所得结果与现有的实验和理论结果进行了比较，用于证明斯塔克展宽机制对恒星大气中 Sn II 光谱线的影响。
