摘要

利用调q Nd:YAG激光聚焦Pb-Sc合金样品，在激光诱导击穿实验中测量了9条单电离钪谱线（和1条中性钪谱线）的电子碰撞增宽参数。此外，利用Van Regemorter和Douglas H. Sampson提出的Gaunt因子，用半经验Griem方法对56条单电离钪谱线进行了这些参数的计算。

Theoretical and experimental electron collisions broadening parameters for several Sc II spectral lines of industrial and astrophysical interest

Electron collision broadening parameters of 9 singly ionized scandium spectral lines (and 1 neutral scandium spectral line) were experimentally measured in laser-induced breakdown experiments using a Q-switched Nd:YAG laser focused on Pb-Sc alloy samples. Furthermore, calculations of these parameters were performed for 56 singly ionized scandium spectral lines in the semi-empirical Griem approach using the Gaunt factors proposed by Van Regemorter and those proposed by Douglas H. Sampson.
