摘要：

The spectrum of platinum was observed in the (300-2100) angstrom wavelength region. The (5d(5)+5d(4)6s)-5d(4)6p transition array of five times ionized platinum, Pt VI, has been investigated and 1390 spectral lines have been classified in the region of (399-1564) angstrom . The analysis has led to the determination of the 5d(5), 5d(4)6s and 5d(4)6p configurations. A1137 theoretically possible 5d(5) levels, 46 of 63 possible 5d(4)6s levels and 167 of 180 possible 5d(4)6p levels have been established. The orthogonal operators technique was used to calculate the level structure and transition probabilities. The energy parameters have been determined by the least squares fit to the observed levels. Calculated transition probability and energy values, as well as LS-compositions obtained from the fitted parameters are presented. The uncertainties of the established energy levels and calculated (Ritz) wavenumbers are included. (C) 2016 Elsevier Inc. All rights reserved.
