Ne → VII n=3，$Δn=0$跃迁Stark宽度的量子力学计算
Quantum-mechanical calculation of Stark widths of Ne VII n=3, $Δn=0$ transitions
摘要：
在碰撞近似下，用量子力学会聚密耦合近似和库仑玻恩交换近似计算了Ne VII 2s 3s-2s 3 p单重线和三重线的斯塔克宽度。结果表明，非弹性碰撞对线宽的贡献超过弹性宽度贡献约一个数量级。与在热稠密等离子体的气体衬套箍缩测量的线宽的比较表明，一个显着的差异，这可能是自然的解释从持续的内爆速度或湍流的箍缩内爆过程中开发的非热多普勒效应。从不同的分波和类型的相互作用的线宽的贡献进行了讨论。
英文摘要：
The Stark widths of the Ne VII 2s3s-2s3p singlet and triplet lines are calculated in the impact approximation using quantum-mechanical Convergent Close-Coupling and Coulomb-Born-Exchange approximations. It is shown that the contribution from inelastic collisions to the line widths exceeds the elastic width contribution by about an order of magnitude. Comparison with the line widths measured in a hot dense plasma of a gas-liner pinch indicates a significant difference which may be naturally explained by non-thermal Doppler effects from persistent implosion velocities or turbulence developed during the pinch implosion. Contributions to the line width from different partial waves and types of interactions are discussed as well.
