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…
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(…
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…
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…
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…
