Abstract

The hyperfine structure of several lines of the spectrum of cobalt between 4000 and 4300 Å has been analyzed using the technique of high-resolution spectroscopy. As a result, the value of the magnetic hyperfine structure constant for 32 states has been found. The classification for four of the lines has also been inferred from the observed hyperfine structure patterns.
