The XUV spectra from AgXIX of laser-produced plasma are measured. The density dependence of △n= 0 (4-4) transitions from AgXIX has been studied in a density range 1017-1022 cm-3 with the collisional radiative model. The theoretical model included the effect of cascading from n= 5 states on the population of the n =4 levels. In addition, optical depth effects on the line intensities were considered. The two transitions of 4d2D5/2 4f2F7/2 and 4p2P3/2-4d2D5/2 remain close to each other and are unblended with other lines. Calculations of their radiation intensity ratio vs the electron density are performed. Electron density of laserproduced plasma has been deduced from the ratio.
