Theoretical investigations on the 3d(9)4p-3d(10) spectrum of CuII

The low-lying lever structure and the 3d(9)4p - 3d(10) resonance and interc ombination transitions of the spectrum CuII have been studied by using larg e-scale multiconfiguration Dirac-Fock wavefunctions. Excitation energies an d transition probabilities are calculated by including all dominant effects of relativity, correlation, and of the rearrangement of the electron densi ty within the same framework. Comparison with experiment and previous compu tations is made which shows a remarkable improvement in the accuracy of the theoretical results. (C) 2001 Elsevier Science B.V. All rights reserved.
