Calculations of the High Lying (2pns) ~(1,3)P° and (2pnd) ~(1,3)P° Rydberg States of the Be Atom via the Modified Atomic Orbital Theory

摘要

We report in this paper on the energy positions of the (2pns) ~(1,3)P° and (2pnd) ~(1,3)P° and the resonance widths of the (2pns) ~1P° (n = 3-25) doubly excited states of the beryllium atom. The calculations are performed using the modified atomic orbital theory (MAOT). The present results compared very well with the available theoretical and experimental literature values. The high precision data presented in this work may be a useful guideline for those studying the photoabsorption spectra of Be.
