Abstract

Transitions of the type 3p⁶ 3d⁸–3p⁵ 3d⁹ in Sb²⁵⁺ have been identified in the spectrum from a plasma produced by irradiating a planar foil target, using line-focused laser irradiation. The wavelengths in the range 44–62 Å were determined with an uncertainty of ±0.007 Å. Based on the 45 observed wavelength combinations, energy-level values were established for 9 levels of the 3p⁶3d⁸ configuration and 12 levels of the 3p⁵3d⁹ configuration with an uncertainty of 200 cm⁻¹. The wavelengths and energy levels were compared with previously observed and predicted values.
