Theoretical Studies of Quadruply Ionized Radon (Rn V) for Energetically Low Lying Levels

Abstract

We have reported the energies and transition parameters for allowed transition (electric dipole, E1), and forbidden transitions (electric quadrupole, E2, and magnetic dipole, Ml) for quadruply ionized radon (Rn V, Z = 86) for energetically low lying levels. The present results were performed using two independent computational strategies of the Hartree-Fock calculation with relativistic corrections and superposition of configurations (Cowan's HFR method) and the general-purpose relativistic atomic structure package based on the fully relativistic multiconfiguration Dirac-Fock (MCDF) method. We have compared our results with the results available in the literature to assess the accuracy of the data. We predict that new energy levels and transition parameters, where no other experimental or theoretical results are available, will form the basis for future experimental work.
