Semi-empirical predictions of energy levels, their Landé [formula omitted] factors and hyperfine structure for the odd-parity configuration system of Ho II

Abstract

We present the results of semi–empirical calculations of the fine (fs) and the hyperfine structure (hfs) for the odd–parity level system of the holmium ion (Ho II), using all available data. A parametric analysis, both for a fs and hfs, for 5 configurations with all the 4f10 and 4f11 core states, by taking into account the second–order effects of perturbation theory, was performed for the first time.The predicted energies of electronic levels together with their Landé gJ factors as well as magnetic dipole A and electric quadrupole Bhfs constants for unknown levels are listed.The importance of the Landé gJ factors in atomic and quantum physics, as well as a complete lack of experimental data on this subject, make our calculated values all the more useful.
