First \textit{ab initio} calculations of first-forbidden transitions in the reactor antineutrino anomaly

X. Y. Xu, Z. Y. Meng, Z. C. Xu +1

Forbidden transitions are important for understanding the reactor antineutrino anomaly. Starting from chiral two- plus three-nucleon forces, we have derived the valence-space e…

Magicity Revealed by the Mass of the Proton Dripline Nucleus Si

Y. M. Xing, Y. F. Luo, Y. H. Zhang +36

Using the -defined isochronous mass spectrometry technique, we conducted the first mass measurement of the proton dripline nucleus Si. We confirm that Si is bound…

The renormalization of the shell-model GT operator starting from effective field theory for nuclear systems

L. Coraggio, N. Itaco, G. De Gregorio +5

For the first time, we approach in this work the problem of the renormalization of the Gamow-Teller decay operator for nuclear shell-model calculations by way of many-body perturba…

The role of three-nucleon potentials within the shell model: past and present

L. Coraggio, G. De Gregorio, T. Fukui +4

We survey the impact of nuclear three-body forces on structure properties of nuclei within the shell model. It has long been acknowledged, since the seminal works of Zuker and cowo…

Complex valence-space effective operators for observables: the Gamow-Teller transition

Z. C. Xu, S. Zhang, J. G. Li +5

Nuclei in the vicinity of driplines have been receiving a lot of attention in nuclear structure studies. In the nuclei, the continuum coupling is crucial in reproducing weakly-boun…
