最近的实验和理论（无论是改进的半经典和完全量子力学）的结果B III和Ne VII δ n = 0的过渡与n = 2或3，分别进行了讨论。完全量子力学计算的宽度与测量的和半经典计算的宽度之间存在约2倍的分歧，其可能原因可以解释为违反有效性准则和非热多普勒效应。对于多重电离的非类氢离子，需要更独立地确定谱线宽度，但同时在使用相应的半经典计算宽度时应谨慎，例如，用于不透明度计算或等离子体密度诊断。只有量子计算允许一个明确的分离的弹性和非弹性散射的贡献的宽度。对于B III，弹性散射贡献约30%，而对于Ne VII，非弹性散射占主导地位。这允许与基准电子-离子散射实验进行相当直接的比较。
英文摘要：
Recent experimental and theoretical (both improved semiclassical and fully quantum-mechanical) results for B III and Ne VII delta n = 0 transitions with n = 2 or 3, respectively, are discussed. The probable reasons for disagreements by about a factor of 2 between the fully quantum-mechanically calculated and both measured and semiclassically calculated widths can be explained in terms of violation of validity criteria and non-thermal Doppler effects. More independent determinations of line widths for multiply-ionized non-hydrogenic ions are called for, but meanwhile caution should be exercised in the use of corresponding semiclassically calculated widths, e.g., in opacity calculations or for plasma density diagnostics. Only the quantum calculations allow a clear separation of elastic and inelastic scattering contributions to the width. For B III, elastic scattering contributes about 30% whereas for Ne VII inelastic scattering dominates. This allows rather direct comparisons with benchmark electron-ion scattering experiments.
