E1 AND M2 TRANSITIONS IN THE NEON ISOELECTRONIC SEQUENCE

Using relativistic and nonrelativistic Hartree-Fock methods we have calculated some E1 and M2 transition probabilities for 2p53d and 2p53s 2p6+ in the Ne isoelectronic sequence. The heaviest ion considered is U. The relativistic effects on both the photon energies and the transition amplitudes are discussed. A comparison of our calculated M2 lifetimes with experimental results for the 2p53s-2p6 transition in Ne-like Cu shows significant differences, while the calculated E1 lifetimes for Ne-like Cl indicates good agreement with experiment. © 1979 The American Physical Society.
