Abstract: | The hfs and hfs Zeeman splitting of nine lines from the array 6p7p→6p7s as well as lines λ = 496.9 nm (6p8p 3D2→6p7s 3P2) and λ=581.8 nm (6p8s 3P0→6p7p 3D1) of Bi II have been analysed. The Zeeman effect studies were performed for transverse direction of observation and separated π; and σ components of lines. The electrodeless discharge tube containing metallic Bi was used as the light source. The spectral apparatus consisted of a sliver-coated Fabry-Perot etalon and a grating spectrograph combined with a diode array detector. In the analysis of the spectra we used the computer simulation technique. The magnetic-dipole (A) and the electric-quadruple (B) hfs constants as well as Lande-gj factors for the level 6p8p 3D2 and all levels of configurations 6p7s and 6p7p (with the exception of 6p7p 3S1) were determined. Our results are compared with recent theory and other experiments. |
