The spectra of highly ionized scandium, titanium, vanadium and chromium emitted from laser-produced plasmas have been recorded in the region 270–600 Å. The radiation from a Quantel NG24 Nd:YAG/glass laser giving the maximum energy 4J in 3ns pulses was focused on plane metal targets. The target was placed at the Sirk’s focus of a 3-m normal incidence spectrograph with the target surface parallel to the slit. The laser beam was perpendicular to the target and to the entrance axis of the spectrograph. By this arrangement the spectral lines from different ionization stages differ in length, the highest states giving the shortest lines. Well-determined lines from spark recordings of sodium-, magnesium-, aluminium-, and silicon-like ions were used for the wavelength determinations.
