Atomic triply excited double Rydberg states of lanthanum investigated by selective laser excitation - art. no. 031402

摘要

The atomic triply excited double Rydberg states (TEDRS) of La have been studied both experimentally and theoretically. It is revealed that in such an asymmetric four-body system where three electrons have very different orbital energies, the electronic correlations can be understood by means of decomposing into different dielectronic correlations that play different roles time-dependently. The correlations depend strongly on the relative excited orbital energies of three valence electrons. Our theoretical approach based on a semiclassical model is able to interpret the two observed patterns of La ion distributions among high Rydberg states resulted from the decay of TEDRS.
