Study of the energy levels of erbium ethylsulphate crystals

“…Table 24 gives the magnetic behavior of 17 levels not given by Smith (43) or Hellwege «t alii (44). Together, Tables 24 and 25 list 24 pairs of levels at zero field which are not given by Smith, Hellwege et alii, Erath (45,Hufner (46) or Wong (47) Table A-2. Character table for the C^^ double group Irreducible Group elements Transformation properties representations and characters of dipole…”

Absorption spectrum and Zeeman effect of dysprosium ethylsulfate

“…Many workers (54)(55)(56)(57)(58)(59)(60)(61)(62) but here, since the magnetic splittings were not small com pared to the crystal field splittings, it was necessary to follow the extended theory outlined in reference (51) in order to explain the energy changes observed on rotation for a system with an even number of 4f electrons.…”

Absorption spectrum and Zeeman effect of dysprosium ethylsulfate

“…Many workers (54)(55)(56)(57)(58)(59)(60)(61)(62) have used these valuable tools to calcu late matrix elements, energy levels, eigenfunctions, and to fix theoretical parameters determining the electrostatic, spin-orbit, and crystal field interactions by least squares fitting of the experimental data. The aim of these calcula tions has largely been to explore the possibilities and limitations of a necessarily simplified theoretical model following Condon and Shortley, Although energy levels cal culated with the parameters obtained in this way often agree with the experimentally determined levels within one percent, the experimental energies can be measured to within one part in 10 .…”
