Laser-produced spectra of sodium-like ions Cu XIX-Br XXV were studied in the region 20-300 A. About 50 new lines, mainly due to transitions n = 3 - n' = 5 to 7 and n = 4 - n' = 5, have been identified and wavelengths of known lines have been revised. Energy structure and ionization limits are derived.
