摘要: 激光等离子体M带0.346~0.372nm范围内精细结构谱,是金等离子体的类Co、类Ni、类Cu、类Zn离子的3d-5f、3p-5s跃迁子阵形成的。在自旋轨道劈裂阵模型下, 对平均波长在该范围内的各子阵的主要特征参数如平均波长、半高宽和总跃迁强度进行详细计算,得到与实验测量基本一致的结果,可用于等离子体的精确诊断。Abstract: The spectrum of a laserproduced plasmas of gold in the range 0.346 ~0.372nm is considered as the production of the spinorbitsplit arrays of the 3d5f、3p5s transitions for Au 49+Au 52+. The main characteristic parameters, mean wavelength, the full width at half maximum and total transition intensity,of subarrays whose mean wavelength belongs to the above range is computed in detail by means of spinorbitsplit array model,the excellent agreement between theoretical calculation and experiment indicates the possibility o f use for precise diagnostics of plasmas.
