The octet S72 ground state Gd3 is split only 0.149cm by the cubic crystal field in CaF2 and is described at 11.3 kG by the projection quantum number J sub Z referred to the magnetic field axis and behaves like a spin 72 system with an isotropic g value of 1.991. The excited states are most conveniently described with reference to the 4-fold axes. The calculation of the dependence of the Zeeman spectra of Gd3 in CaF2 at sites of cubic symmetry on crystal orientation, therefore, requires transformation of one set of basis to a common Cartesian reference frame. The Zeeman spectra shows the states of the crystal field split hextet P72 and hextet P52 multiplets. The transitions are magnetic dipole in agreement with the results for other rare earth ions at cubic sites. Experimental and calculated splittings are compared. Author
