“…Combined with accurate measurements of hyperfine structure splittings, calculated atomic parameters can be used to extract nuclear quadrupole moments Q [3]. In a different setting the hyperfine interaction is a key factor in determining excited state nuclear g-factors from recoil-in-vacuum experiments [4]. Hyperfine interaction is also important in astrophysics, high resolution solar, stellar spectra reveal isotope shifts and hyperfine structures of many spectral lines.…”

Energy levels, hyperfine interaction constants, and Landé g J -factors are reported for n = 2 states in beryllium-, boron-, carbon-, and nitrogen-like ions from relativistic configuration interaction calculations. Valence, core-valence, and corecore correlation effects are taken into account through single and double-excitations from multireference expansions to increasing sets of active orbitals. A systematic comparison of the calculated hyperfine interaction constants is made with values from the available literature.

“…To date we have used a semiempirical method to define G k (|g|τ) [1,2,3,8,9]. It appears, however, that ab initio calculations of the relevant atomic physics may be possible in future [10,11]. This experimental and calculational effort, along with the current open questions, has been reviewed recently [9].…”

Abstract. Several g-factor measurements have been performed recently on nuclei near the neutron-rich, double-magic nucleus 132 Sn. The focus here is on 134 Te, the N = 82 isotone which has two protons added to 132 Sn. The electromagnetic properties of 134 Te are examined. Comparisons are made with other nuclei that have two protons outside a double-magic core. The extent to which 132 Sn is an inert core is discussed based on these comparisons. The electromagnetic properties of the N = 82 isotones from 132 Sn to 146 Gd are also discussed.

“…Stone et al [39] have reported such calculations for Mo, Ru and Pd ions recoiling into vacuum with velocity v/c ∼ 0.05, and more recently for 54,56 Fe ions at v/c ∼ 0.08 [40]. This static model can then be improved by including the effect of atomic transitions, based on the calculated atomic level lifetimes, which Stone et al also explored [39,40]. Chen et al [21] have taken the calculations further by implementing a Monte Carlo method to evaluate the effect of atomic transitions and applying it to the tellurium isotopes.…”

The g factor of the first 2 + state of radioactive 136 Te with two valence protons and two valence neutrons beyond double-magic 132 Sn has been measured by the Recoil in Vacuum (RIV) method. The lifetime of this state is an order of magnitude longer than the lifetimes of excited states recently measured by the RIV method in Sn and Te isotopes, requiring a new evaluation of the free-ion hyperfine interactions and methodology used to determine the g factor. The calibration data are reported and the analysis procedures are described in detail. The resultant g factor has a similar magnitude to the g factors of other nuclei with an equal number of valence protons and neutrons in the major shell. However, an unexpected trend is found in the g factors of the N = 84 isotones, which decrease from 136 Te to 144 Nd. Shell model calculations with interactions derived from the CD Bonn potential show good agreement with the g factors and E2 transition rates of 2 + states around 132 Sn, confirming earlier indications that 132 Sn is a good doubly magic core.
