Improved Critical Compilations of Selected Atomic Transition Probabilities for Neutral and Singly Ionized Carbon and Nitrogen

Abstract

We have undertaken new critical assessments and tabulations of the transition probabilities for important lines of neutral and singly ionized carbon and nitrogen. Our updates primarily address the persistent lower transitions as well as a greatly expanded number of forbidden lines (M1, M2, and E2 lines). For these transitions, sophisticated multiconfiguration Hartree-Fock (MCHF) calculations have been recently carried out, which have yielded data considerably improved and often appreciably different from our 1996 NIST compilation.
