Forbidden transition properties of fine-structure 2p3 4S3/2-2p3 2D3/2,5/2 for nitrogen-like ions

doi:10.1088/1674-1056/27/8/083102

Abstract

Based on relativistic wave functions from multiconfiguration Dirac-Hartree-Fock and configuration interaction calculations, E2 and M1 transition probabilities of 2p^{3 4}S_3/2-2p^{3 2}D_3/2,5/2 are investigated in the nitrogen-like sequence with 7 ≤ Z ≤ 16. The contributions of the electron correlations, Breit interaction, and the quantum electrodynamic (QED) effects on the transition properties are analyzed. The present results can be used for diagnosing plasma. In addition, several N-like ions can also be recommended as a promising candidate for a highly charged ion (HCI) clock with a quality factor (Q) of transition as high as 10²⁰.

Keywords: forbidden transition probabilities nitrogen-like ions MCDHF method RCI
