-forbidden strengths near Sn from knockout reactions in Cd and Sn
T. J. Gray, K. L. Jones, R. Grzywacz +21
Neutron knockout reactions on beams of Cd, and Sn are presented. States in the residual Cd and Sn nuclei are populated, including low-lying…
Taming nuclear size and shape effects in superallowed beta-decay
Bingcheng He, Mikhail Gorchtein, Matthias Heinz +3
We present the first combined analysis of the statistical rate function f in superallowed beta decays with ab initio calculations and data. We focus on C10 to 10B, 14O to 14N and 2…
Ab initio calculation of symmetry-breaking observables
A Belley, B. Romeo, J. Engel +8
Symmetry-violating observables such as the nuclear anapole and Schiff moments provide sensitive probes of the fundamental symmetries of nature and physics beyond the Standard Model…
In-medium similarity renormalization group for a pairing-plus-particle-hole model
L. H. Chen, Y. G. Yao, B. C. He
We benchmark two implementations of the in-medium similarity renormalization group (IMSRG) method, IMSRG(2) and IMSRG(2*), for the low-lying states of a pairing-plus-particle-hole…
Improving the predictive power of empirical shell-model Hamiltonians
J. A. Purcell, B. A. Brown, B. C. He +2
We present two developments which enhance the predictive power of empirical shell-model Hamiltonians for cases in which calibration data are sparse. A recent improvement in the ab…
