SPATIAL DISTRIBUTIONS OF X-RAY LASING LINEWIDTH AND ELECTRON DENSITY IN A Li-LIKE SILICON PLASMA

Through analysizing the spatial distribution characteristics of the linewidth of Li-like si-licon ions X-ray lasers, we show that Stark broadening is the main line broadening me-chanism for Li-like Si 11+ ions recombine X-ray laser. Spatial distribution of the electron den-sity of gain medium obtained by Stark brcadening shows that the electron density in the gain region is about 10 19 /cm 3 , and the lasing linewidth and electron density are 0.21? and 2.9 × l0 19 /cm 3 at the gain maximum respectively.
