Theoretical Study of Energy Levels and Transition Probabilities of Singly Ionized Aluminum (Al II)

Abstract

Within the Weakest Bound Electron Potential Model (WBEPM) theory, calculations for energy levels and transition probabilities of singly ionized aluminum (Al II) are performed, and good agreement with experimental or accepted values is obtained. To treat properly the perturbed states, foreign perturbers are taken into account in studying the energy levels, meanwhile, a set of coupled equations is employed to determine the parameters effective nuclear charge Z′, effective principal quantum number n′, and effective angular quantum number l′ needed for the calculation of transition probabilities.
