Relativistic configuration interaction plus linearized-coupled-cluster calculations of U2+ energies, g factors, transition rates, and lifetimes
AltmetricsView Usage Statistics
Excitation energies, term designations, g factors, transition rates, and lifetimes of U2+ are determined using a relativistic configuration interaction (CI) + linearized-coupled-cluster (LCC) approach. The CI-LCC energies are compared with CI + many-body-perturbation-theory (MBPT) and available experimental energies. Close agreement has been found with experiment, within hundreds of cm(-1). In addition, lifetimes of higher levels have been calculated for comparison with three experimentally measured lifetimes, and close agreement has been found within the experimental error. CI-LCC calculations constitute a benchmark test of the CI + all-order method in complex relativistic systems such as actinides and their ions with many valence electrons. The theory yields many energy levels, g factors, transition rates, and lifetimes of U2+ that are not available from experiment. The theory can be applied to other multivalence atoms and ions, which would be of interest to many applications.
