Abstract
The negative osmium ion is one of very few atomic anions potentially suitable for laser cooling. We have made a measurement of the Zeeman splitting of a bound-bound transition in by studying the laser excitation from the 56 ground to the 566 excited state in a homogeneous external magnetic field. The experimental Landé factors and , respectively, agree well with calculated values. Both levels are found to split into 10 Zeeman sublevels, resulting in 28 allowed transitions of different relative intensities, in agreement with calculations based on pure and composite states. In view of the experimental results, the prospects for laser cooling of are discussed.
