Island of Inversion in neutron-rich cobalt isotopes revealed from mass measurements

M. Flayol, P. Ascher, D. D. Dao +19

Mass measurements of the ground and isomeric states of Co have been performed using the JYFLTRAP Penning-trap mass spectrometer at the IGISOL facility. The masses were me…

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 be…

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…

Isomeric yield ratios and mass spectrometry of Y and Nb isotopes in the neutron-rich N=60 region: the unusual case of Y

Simone Cannarozzo, Stephan Pomp, Anu Kankainen +14

The isomeric yield ratio (IYR) of fission products is an observable that carries relevant information about the fragments emerging from the scission of a fissioning nucleus. We rep…

High-precision direct decay energy measurements of the electron-capture decay of Tc

Zhuang Ge, Tommi Eronen, Vasile Alin Sevestrean +27

A direct measurement of the ground-state-to-ground-state electron-capture decay () value of Tc has been conducted employing the high resolving power phase-im…

Disentangling the influence of excitation energy and compound nucleus angular momentum on fission fragment angular momentum

Simone Cannarozzo, Stephan Pomp, Andreas Solders +14

The origin of the large angular momenta observed for fission fragments is still a question under discussion. To address this, we study isomeric yield ratios (IYR), i.e. the relativ…
