HIGH-RESOLUTION X-RAY SPECTROSCOPY OF PLASMA PRODUCED BY INTENSIVE PICOSECOND LASER-PULSE

It is experimentally shown that the radiation source based son Picosec ond laser plasma is very perspective for systematic study of multychar dge ions sattelite structures, that have electrons on L- or M-shells. Unique characteristics of the source together with registering system used (spectral resolution DELTAlambda/lambda approximately 10(-4)) per mitted to define more precisely linewidthes of some iones MgIX, X tran sitions, which where identified earlier, for the first time to identif y 10 spectral lines due to 1s2p4l --> 1s(2)4l and ls2p3l --> 1S(2)3l t ransitions of MgX ion, as well as to measure the linewidthes of 47 spe ctral which supposed to belong to Be-like MgIX ion.
