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…
Probing the quantum phase transition around via mass measurements of technetium isotopes
J. Ruotsalainen, A. Jaries, M. Stryjczyk +28
The masses of neutron-rich Tc isotopes were measured using the JYFLTRAP double Penning trap and found to deviate from the Atomic Mass Evaluation 2020 by , $40(…
High-resolution multi-reflection time-of-flight mass spectrometer for exotic nuclei at IGISOL
V. A. Virtanen, T. Eronen, A. Kankainen +9
A Multi-Reflection Time-of-Flight Mass Spectrometer (MR-ToF-MS) has been commissioned at the Ion-Guide Isotope Separator On-Line (IGISOL) facility. It consists of six electrode pai…
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…
