摘要：
The spectrum of the 4p(6)4d(7)-(4p(6)4d(6)4f + 4p(5)4d(8)) transitions in Sn VIII occurring in the wavelength range 140-170 angstrom and excited in a vacuum spark plasma was investigated. For the first time, 113 spectral lines of these transitions were classified and the energies of 38 levels of the 4d(6)4f and 4p54d8 configurations were experimentally determined. The semiempirical energy parameters determined by least-squares fitting of the experimental energies of Sn VIII are in good agreement with the parameters of the corresponding configurations obtained previously in the analysis of the Sn VI and Sn VII spectra.
