A priori calculations of hyperfine interactions in highly ionized atoms: G-factor measurements on aligned pico-second states populated in nuclear reactions

Hyperfine Interactions 197:1 (2010) 29-35

Authors:

NJ Stone, JR Stone, P Jonsson

Abstract:

Calculations of hyperfine interaction strength and life-times of states in highly ionized atoms, using the GRASP atomic structure package, are reported. The calculations aim at providing calibration for Recoil-in-Vacuum nuclear excited state g-factor measurements. The method is outlined and results compared with experiment. Inclusion of decay of higher electronic states is discussed. © 2010 Springer Science+Business Media B.V.

Odd-parity bands ^{108, 110, 112}Ru

Abstract:

Two similar sets of odd-parity bands are observed in each of three eveneven neighbors, 108, 110, 112Ru, from a study of prompt spontaneous-fission gamma rays at Gammasphere. A careful study of the odd-parity levels of these nuclei shows evidence for the features of chiral doubling. Comparisons are made with reported other candidates for chiral doubling. © 2009 World Scientific Publishing Company.
