First evidence for the J1 components of the pygmy dipole resonance in neutron-rich nuclei
R. Li, E. Litvinova, M. N. Harakeh +21
Gamma () decay shapes the synthesis of heavy elements in neutron-rich nuclear environments of neutron star mergers, supplying the Universe with heavy elements. The low-energy p…

-delayed spectroscopy of Ge and competition between Gamow-Teller and first-forbidden transitions in Ga decay
R. Li, D. Verney I. Matea, M. N. Harakeh +28
The -delayed spectroscopy of Ge has been studied using sources of ground and low-lying isomeric states of Ga. A hybrid -ray spectrometer was used, composed of…

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…
