The renormalization of the shell-model neutrinoless double-beta decay operator starting from effective field theory (I)
L. Coraggio, G. De Gregorio, S. L. Lyu +1
In this work, we approach for the first time the task to perform a shell-model calculation of the matrix element for the neutrinoless double-beta decay, within a fully-consistent f…

Realistic shell model for ordinary muon capture of sd-shell nuclei
S. L. Lyu, G. De Gregorio, T. Fukui +2
We report about a study of the ordinary muon capture in nuclei belonging to the sd shell, an electroweak process that occurs with exchange momenta far larger than ordinary beta dec…

Simultaneous impacts of nuclear shell structure and collectivity on decay: Evidence from Ga
R. Li, D. Verney, G. De Gregorio +32
The Gamow-Teller strength distribution covering the entire -decay window, up to 10.312(4) MeV, of Ga was measured for the first time in photo fission of UC induce…
