Study of Decay Shape Factors in First-Forbidden Transitions with for Reactor Antineutrino Spectra Predictions
G. A. Alcalá, A. Algora, M. Estienne +36
The electron spectra of the decays of Rb and Cs, key contributors to the reactor antineutrino spectrum, were measured at the IGISOL facility using radioactive b…
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…
Study of beta spectrum shapes relevant to the prediction of reactor antineutrino spectra
G. A. Alcalá, A. Algora, M. Estienne +35
The shapes of the beta spectra of 92Rb and 142Cs, two of the beta decays most relevant for the prediction of the antineutrino spectrum in reactors, have been measured. A new setup…
High-precision mass measurements of the ground and isomeric states in Ag
J. Ruotsalainen, D. A. Nesterenko, M. Stryjczyk +26
The masses of the ground and isomeric states in Ag have been measured using the phase-imaging ion-cyclotron-resonance technique at the JYFLTRAP double Penning trap mass…
