摘要
将千兆瓦大功率钕玻璃激光装置发出的激光束聚焦于固体平面铝靶上,产生一高温、高密度等离子体,用1米掠入射式凹面光栅摄谱仪记录了等离子体在50—110(?)波长范围内的发射光谱。用HXR自洽场方法和非线性最小二乘法拟合方法相结合,对铝的高离化态离子谱线和相应的能级进行了分析和计算,共辨认和归类属于AlⅤ、AlⅥ、AlⅧ、AlⅧ和AlⅩ离子的新谱线61条。
The emission spectra of ionized aluminium have been recorded photographically in 50-110(?) wavelength region with a one meter grazing incidence spectrograph in a laserproduced plasma. Based on the result of HXR self-consitent field method and non-liner least-square optimization calculation, 61 new lines of aluminium belonging to the AlⅤ、AlⅥ、AlⅦ、AlⅧ、AlⅩ ions are classified
