Anomalous structure of the intensities of the spectral lines of the Ne-like ions CuXX and GeXXIII, emitted by a plasma produced by picosecond laser pulses with flux densities of up to 2 Χ 1018 W/cm2, was recorded for the first time. It is shown that the maximum of the emission spectra of these ions occurs from the region of the plasma where the density is much higher than the critical density for the wavelength of the heating laser radiation. © 1995 American Institute of Physics.
