79. Heavy-ion double-charge-exchange and its relation to neutrinoless double-𝛽 decay

Elena Santopinto (INFN)

5/31/19, 9:00 AM

Oral Presentation

Recent theoretical results on the relation between Heavy-ion double-charge-exchange and neutrinoless double-𝛽 decays will be presented and discussed.

80. Neutrino Mass and High-Precision Penning-Trap Mass Spectrometry

Dr Sergey Eliseev (Max-Planck Institut für Kernphysik)

5/31/19, 9:30 AM

Oral Presentation

The neutrino mass is still unknown. Currently a few experiments, namely KATRIN, HOLMES and ECHo, are built with the ultimate goal to reach a sub-eV/c2 uncertainty in the neutrino-mass determination from the analysis of two nuclear beta-decays: beta-decay of tritium and electron capture in 163Ho. All these experiments demand directly and independently determined Q-values of these...

81. Precise measurement of two-neutrino double-beta decay of 100Mo with lithium molybdate low temperature detectors

Prof. Fedir Danevych (Institute for Nuclear Research, Kyiv, Ukraine)

5/31/19, 10:00 AM

Oral Presentation

The two-neutrino double-beta decay of 100Mo was investigated with the help of enriched in 100Mo lithium molybdate scintillating bolometers. The measurements were performed in the EDELWEISS-III low background set-up in the Modane underground laboratory with a total exposure of 42.235 kg x d. Preliminary, the half-life of 100Mo with respect to the two-neutrino double-beta decay to the ground...
