Abstract
For most symmetries the standard parametrization of one-photon electric-dip ole transitions between crystal-field levels of the 4f(N) configuration of lanthanide ions produces identical intensities for several quite different parameter sets. An alternative scheme makes this multiplicity transparent a s independent sign choices for each subset of parameters corresponding to d istinct polarizations. In addition, the alternative parametrization allows separate fits to data for different polarizations. [S0163-1829(99)51212-5].
