Abstract
To reduce the discrepancies in the crystal-field analyses of the electronic configurations of lanthanide ions, it is argued that each component of the single-electron tensor for electron occurring in the conventional crystal-field Hamiltonian should be augmented to . Parameters of the order of - 0.1 lead to significant improvements in the fit with a wide variety of experimental data.
