We report a study of the 2p 5 3s, 3p and 3d con¢gurations of Ne-like Br XXVI, by means of beam foil spectroscopy. In the region 100^300 Ð more than 20 Br XXVI lines were identi¢ed, 5 of which were known earlier, from X-ray laser work. Experimental energies for the 3s, 3p and 3d levels are compared with results of relativistic Hartree-Fock (HFR) calculations. We also present predicted 3s-3p and 3p-3d wavelengths, obtained by combining the new Br results with data for other Ne-like ions.
