Abstract : An elementary analysis of the crystal-field splittings, Zeeman Effect, and line strengths for the magnetic dipole transitions for GdCl3.6H2O is presented. It is assumed that the environment of the gadolinium ion can be represented by a static electric field. The crystal-field calculation is based on the hypothesis that the ion is at a site of pseudo-cylindrical symmetry. A fit of the data for the septet P(7/2) and septet P(5/2) levels yields B(o)2 = -281.70/cm and B(2)2 = -75.42/cm for the crystal field parameters. The intermediate - coupling g values are in close agreement with those calculated from the observed sum rules of the Zeeman splittings. (Author)
