ANALYSIS OF THE SPECTRUM OF 5 TIMES IONIZED OSMIUM (OS-VI)

The analysis of Os VI has for the even system resulted in the determin ation of all levels (19) in the 5d(3) ground configuration and of 14 l evels out of 16 theoretically possible levels in the 5d(2)6s configura tion. In the odd system all levels (45) of the 5d(2)6p configuration h ave been found. In the 435-765 Angstrom wavelength region 290 lines be longing to the 5d(3)-5d(2)6p transition array have been classified, wh ile in the 940-1510 Angstrom wavelength region 87 lines belonging to t he 5d(2)6s-5d(2)6p transition array were classified. The analysis was guided by predicted energy level values and transition probabilities c alculated by means of a complete set of orthogonal operators. Calculat ed energy values, LS-compositions and gA-values, obtained from the fin al fitted parameter values using the orthogonal operator approach are given.
