CLASSIFICATION OF 3-3 TRANSITIONS IN NEON-LIKE GERMANIUM IN LASER-PRODUCED PLASMA

Classification of 3-3 transitions in neonlike germanium in laser-produ ced plasma has been made. The spectra have been observed in the range of 185-290 angstrom using a high resolving power (lambda/DELTA lambda approximately 13000) grazing-incidence spectrometer in XUV laser exper iment. A total of 21 lines (including five lasing lines) have been cla ssified as transitions between the 2s(2)2p(5)3s, 3p, 3d or 2s 2p(6)3p, 3d and sodiumlike germanium configurations. The identified transition s have been used to derive energy levels of 2s(2)2p(5)3l in neonlike g ermanium. The experimental results have been compared with theoretical predictions from Dirac-Fock (MCDF) calculations.
