| Popis: | In this work investigations of the hyperfine structure of 66 spectral lines of the holmium atom were performed with the method of laser induced fluorescence in a hollow cathode discharge lamp. Altogether 43 odd-parity levels, involved as the upper levels in the transitions studied, were investigated. For about half of them the hfs constants A and B were evaluated for the first time. For some levels, already examined in earlier works, supplementary results were obtained; for a few levels it was possible to compare our results with earlier literature data. For 4 levels J quantum numbers were changed with respect to the available literature values. As a by-product, also improved hfs constants for the lower even-parity levels were determined. The data reported facilitated the semi-empirical fit of the fine and hyperfine structure of the odd-parity level system, performed in our group. |
