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…
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…
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…
Performance of the MORA Apparatus for Testing Time-Reversal Invariance in Nuclear Beta Decay
N. Goyal, A. Singh, S. Daumas-Tschopp +40
The MORA experimental setup is designed to measure the triple-correlation D parameter in nuclear beta decay. The D coefficient is sensitive to possible violations of time-reversal…
