A Critical Compilation of Atomic Transition Probabilities for Singly Ionized Argon

Abstract

We have critically compiled the atomic transition probabilities of Ar ii lines by combining recent high-accuracy lifetime data with branching-ratio emission measurements. We present several comparisons of the various literature data, including theoretical results, and we discuss our assessment procedure in detail. On the basis of this procedure, we present an extension list of critically evaluated transition probabilities with uncertainty estimates.
