The time differential perturbed angular distribution technique with LaBr3 detectors has been applied to the Iπ=11/2− isomeric state (Ex = 846 keV, τ=107 ns) in 107Cd, which was populated and recoil-implanted into a gadolinium host following the 98Mo(12C, 3n)107Cd reaction. The static hyperfine field strength of Cd recoil implanted into gadolinium was thus measured, together with the fraction of nuclei implanted into field-free sites, under similar conditions as pertained for a previous implantation perturbed angular distribution
g-factor measurement on the Iπ=10+ state in 110Cd. The 110Cd g(10+) value was thereby reevaluated, bringing it into agreement with the value expected for a seniority-two νh11/2 configuration.

[preprint] Effective field theory for nuclear vibrations with quantified uncertainties

Effective field theory for nuclear vibrations with quantified uncertainties

arXiv: 1510.02401

We develop an effective field theory (EFT) for nuclear vibrations. The key ingredients – quadrupole degrees of freedom, rotational invariance, and a breakdown scale around the three-phonon level – are taken from data. The EFT is developed for spectra and electromagnetic moments and transitions. We employ tools from Bayesian statistics for the quantification of theoretical uncertainties. The EFT consistently describes spectra and electromagnetic transitions for 62Ni, 98,100Ru, 106,108Pd, 110,112,114Cd, and 118,120,122Te within the theoretical uncertainties. This suggests that these nuclei can be viewed as anharmonic vibrators.
