摘要：

Hyperfine structure (hfs) investigations have been performed on a forbidden transition of the Bi I emission spectral line in the visible region at 15,437.49 cm -1, between the levels 6p 3 4 S 3/2 and 6p 3 2 D 5/2, by means of a Fourier Transform spectrometer. Electrodeless discharge lamps (EDL) containing BiI3 were utilized to generate the bismuth plasma. In these observations, all the 6 components of electric quadrupole ( AF = & PLUSMN;2) transitions have been detected for the first time, in addition to the 12 components of magnetic dipole ( AF = 0, & PLUSMN;1) transitions. Magnetic dipole constant ( A ) and electric quadrupole constant ( B ) have been derived for the combining levels.& COPY; 2023 Elsevier Ltd. All rights reserved.
