Satellites to the He-like ion 1s2 1S0-1s3p 1P1 lines with Z = 12-19 in laser plasmas

Abstract
On the basis of relativistic calculations, which include spin–orbit interaction, satellite structure in the vicinity of the 1s21S0 – 1s 3p1P1 line of the He-like ions, with Z = 12−19, has been identified in X-ray emission from a laser plasma. Good agreement between experimental and theoretical values of wavelengths was obtained. The agreement for intensities was satis-factory for some, but not all lines.
