High-resolution spectra of Se xxiv have been obtained with a 3-m grazing-incidence spectrograph. Thin plastic foils coated with selenium were irradiated with four or eight beams of the OMEGA laser in a line-focus configuration. Spectrograms were obtained by viewing the plasma axially. Prominent in the spectra were the 3s–3p and 3p–3d transitions in the 150–240-Å region and the transitions nl–(n + 1)l′ with n = 3, 4 in the 24–80-Å region. We also present the energy levels and ionization limit derived from the measured wavelengths.
