用掠入射光栅光谱仪拍摄了4～12nm波段范围内镁的激光等离子体软X射线发射光谱。利用等电子数序列离子光谱的规律性,对镁的类铍电离级离子跃迁的软X光谱线进行了识别。

The emission spectrum of laser produced magnesium plasma has been recorded photographically in 4-12 nm spectral range by means of P. grazing incidence grating spectro-graph. Using isoelectronie regularities from known spectra of other neighbouring ions, the spectral lines of Be-like magnesium ions have been recognized and many new ones are obtained.
