Comprehensive investigation of fission yields by using spallation- and (p,2p)-induced fission reactions in inverse kinematics
J. L. Rodríguez-Sánchez, A. Graña-González, J. Benlliure +66
In the last decades, measurements of spallation, fragmentation and Coulex induced fission reactions in inverse kinematics have provided valuable data to accurately investigate the…
Probing the Z = 6 spin-orbit shell gap with (p,2p) quasi-free scattering reactions
I. Syndikus, M. Petri, A. O. Macchiavelli +76
The evolution of the traditional nuclear magic numbers away from the valley of stability is an active field of research. Experimental efforts focus on providing key spectroscopic i…
The observation of vibrating pear shapes in radon nuclei: update
P. A. Butler, L. P. Gaffney, P. Spagnoletti +41
There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipol…
Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive Ra and Ra Beams
P. A. Butler, L. P. Gaffney, P. Spagnoletti +40
There is sparse direct experimental evidence that atomic nuclei can exhibit stable pear shapes arising from strong octupole correlations. In order to investigate the nature of octu…
The mutable nature of particle-core excitations with spin in the one-valence-proton nucleus 133Sb
G. Bocchi, S. Leoni, B. Fornal +43
The gamma-ray decay of excited states of the one-valence-proton nucleus 133Sb has been studied using cold-neutron induced fission of 235U and 241Pu targets, during the EXILL campai…

First results are reported on the ground state configurations of the neutron-rich Na isotopes, obtained via Coulomb dissociation (CD) measurements as a method of the dire…
Low-energy Coulomb excitation of Fe and Mn following in-beam decay of Mn
L. P. Gaffney, J. Van de Walle, B. Bastin +26
Sub-barrier Coulomb-excitation was performed on a mixed beam of Mn and Fe, following in-trap decay of Mn at REX-ISOLDE, CERN. The trapping and charge b…
Spectroscopy of Na: shell evolution toward the drip line
A. Lepailleur, K. Wimmer, A. Mutschler +40
Excited states in Na have been studied using the -decay of implanted Ne ions at GANIL/LISE as well as the in-beam -ray spectroscopy at the NSCL/S800 facility. N…
Collectivity in the light radon nuclei measured directly via Coulomb excitation
L. P. Gaffney, A. P. Robinson, D. G. Jenkins +49
Background: Shape coexistence in heavy nuclei poses a strong challenge to state-of-the-art nuclear models, where several competing shape minima are found close to the ground state.…
Study of bound states in 12Be through low-energy 11Be(d,p)-transfer reactions
