Abstract

Transitions in Ge xxiv, Ge xxv, and Ge xxiv were observed in the spectra emitted from linear plasmas that were produced by irradiating planar targets using eight line-focused beams of the Omega laser. A 3-m grazing-incidence spectrograph viewed the plasma in the axial direction. The spectral lines were quite narrow owing to the reduced ion motion along the line of sight. Transitions of the type 2s²2p^j–2s2p^j⁺¹ (where j = 3, 4, 5) and 2s2p^k–2p^k+1 (where k = 4, 5) were observed in the first through fifth spectral orders. The wavelengths were measured with an uncertainty of less than 0.010 Å, and the energy levels were determined with an uncertainty smaller than 100 cm⁻¹.
