复合X光激光中复合阶段拉氏点的特性
-
摘要: 给出了拉氏点在进入Ne/Te增益目标区域后，其电子密度、电子温度、裸核布居概率、类H离子2–1线逃逸概率和增益随时间变化的近似估计式，以及拉氏点进入Ne/Te增益目标区域的时间tg与电子温度Teg必须满足的关系。Abstract: In this paper, approximate expressions of electron density, electron temperature, fractional population of bare nuclei, escape probability of 2 – 1 transition and gain for 3d5/2 – 2p3/2 transition in H –like C ions in expanding plasma from a laser – irradiated carbon fibre are obtained.
