DIELECTRONIC SATELLITES OF THE HE-BETA LINE OF THE SI-XIII ION IN A DENSE LASER-PLASMA

The first precision measurements of the wavelengths and identification s were made of the satellites of the He-beta line of the Si XIII ion i n the emission spectrum of a laser plasma, These satellites were the r esult of radiation decay of the 1s3l(1)2l(2) levels of the Si XII ion. The wavelengths were determined more accurately for the 1s3l(1)3l(2) configurations. The experimental results obtained were compared with c alculations carried out by various methods. The structure of the relat ive intensities of the 1s3l(1)3l(2) satellites indicated that their em ission occurred mainly in a thin overdense plasma region with N-e > N- e(cr).
