Experimental study of Tc-100 beta decay with total absorption gamma-ray spectroscopy Fraile Prieto, Luis Mario Vedia Fernández, María Victoria The beta decay of Tc-100 has been studied by using the total absorption gamma-ray spectroscopy technique at the Ion Guide Isotope Separator On-Line facility in Jyvaskyla. In this work the new Decay Total Absorption gamma-ray Spectrometer in coincidence with a cylindrical plastic beta detector has been employed. The beta intensity to the ground state obtained from the analysis is in good agreement with previous high-resolution measurements. However, differences in the feeding to the first-excited state as well as weak feeding to a new level at high excitation energy have been deduced from this experiment. Theoretical calculations performed in the quasiparticle random-phase approximation framework are also reported. Comparison of these calculations with our measurement serves as a benchmark for calculations of the double beta decay of Mo-100. 2023-06-17T22:10:24Z 2023-06-17T22:10:24Z 2023-06-17T22:10:24Z 2017-07-27 journal article https://hdl.handle.net/20.500.14352/18170 2469-9985 10.1103/PhysRevC.96.014319 eng CHANDA (605203) ENSAR (262010) FPA2011-24553 FPA2014-52823-C2-1-P FPA2015-65035-P AIC-A-2011-0696 FPI/BES-2014-068222 SEV-2014-0398 FPU12/01527 FSE 213503 ST/F012012/1 open access American Physical Society
