Analysis of the spectrum of five times ionized osmium (Os VI)

The analysis of Os VI has for the even system resulted in the determination of all levels (19) in the 5d(3) ground configuration and of 14 levels out of 16 theoretically possible levels in the 5d(2)6s configuration. In the odd system all levels (45) of the 5d(2)6p configuration have been found. In the 435-765 Angstrom wavelength region 290 lines belonging to the 5d(3)-5d(2)6p transition array have been classified, while in the 940-1510 Angstrom wavelength region 87 lines belonging to the 5d(2)6s-5d(2)6p transition array were classified. The analysis was guided by predicted energy level values and transition probabilities calculated by means of a complete set of orthogonal operators. Calculated energy values, LS-compositions and gA-values, obtained from the final fitted parameter values using the orthogonal operator approach are given.
