New Critical Compilations of Atomic Transition Probabilities
Wolfgang L. Wiese, Jeffrey R. Fuhr, Daniel E. Kelleher, Larissa Podobedova
At the National Institute of Standards and Technology (NIST), we are continuing our critical evaluation and compilation work on atomic transition probabilities. We have recently concentrated our efforts on the spectra of Na, Mg, Al, Si and S for all stages of ionization and on Fe I and Fe II. These new compilations represent a drastic improvement in both quantity and quality over earlier NIST publications. We present a number of graphical comparisons in support of our data selections.
