Rare earth ions in a hexagonal field III

Energy levels and magnetic moments of rare earth ions in a crystal field of hexagonal symmetry have been obtained using a Hamiltonian of the form,H=µBgJ⋅H+B40O40+B60(O60+77/8O66). Selected results are presented for all J values appearing in the rate earth series and for values of the parameters covering the situations in which the crystal field is dominant, in whkch the interaction with the magnetic field is dominant and in which the two...
