An experimental verification of the theoretically predicted density enhancement of the dielectronic satellite spectra emitted by multiply charged lithiumlike ions in high-density plasmas is reported. These plasmas were created by the interaction of solid MgF{sub 2} and SiO{sub 2} targets with high-intensity, subpicosecond, ultraviolet laser radiation. Comparisons between the observed and theoretically predicted values for the intensity ratios between two different pairs of dielectronic satellite lines have enabled determinations of electron densities of the order of 10{sup 23} cm{sup {minus}3} to be made in these high-density laser-produced plasmas.
