Precise determination of electron-capture value of Sn decay related to electron neutrino mass measurements
Zhuang Ge, Tommi Eronen, Vasile Alin Sevestrean +15
A high-precision measurement of the electron-capture (EC) decay value for the ground-state-to-ground-state (gs-to-gs) transition of Sn to In has been performed…
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…
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…
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…
Ultra-low value for the allowed decay of Ag confirmed via mass measurements
J. Ruotsalainen, M. Stryjczyk, M. Ramalho +5
The mass of the electron-antineutrino can be determined in dedicated measurements of the spectral shape near the endpoint of a $β^-$ transition, with a low value enh…
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…
