MULTIPLE-SCATTERING THEORETICAL CALCULATIONS AND ANALYSIS FOR THE ELECTRONIC STRUCTRURES OF RYDBERG STATES IN A SODIUM MOLECULE

Based on the independent-particle-approximation and the multiple-scattering self-consistent-field theory, we have systematically calculated the electronic struc-tures of sodium molecular Rydberg series, analysed the quantum defect \mu and the electronic-vibrational interaction (i.e. d\mu /dR). The influences of double excitation configuration on the Rydberg series have been discussed. The electronic structures of Rydberg states and related dynamic behavior in a sodium molecule have been eluci-dated. Our theoretical results are in fair agreement with the available experimental measurements.
