Measurement of the 85Kr specific activity in the GERDA liquid argon

M. Agostini, A. Alexander, G. Araujo, A. M. Bakalyarov et autres

Abstract The radioactive isotope 85 Kr is found in significant quantities in the atmosphere largely due to nuclear industry. Its $${\upbeta }$$ β -decay with a half-life of 10.7 years and a Q-value of 687 keV is a dangerous background source for …

Internal Detector Background from Two-Neutrino Double-Beta Decay in Searches for Neutrinoless Double-Beta Decay of $${}^{{150}}$$Nd

A. R. Amiraslanova, Z. A. Akhmatov, И. Р. Барабанов, A. Veresnikova et autres

The internal detector background arising in searches for neutrinoless double-beta decay of the isotope $${}^{150}$$ Nd from the two-neutrino beta decay of the same isotope is calculated. The calculation is performed for a detector several liter in volume based on a neodymium-doped …

Searches for new physics below twice the electron mass with GERDA

M. Agostini, A. Alexander, G. Araujo, A. M. Bakalyarov et autres

Abstract A search for full energy depositions from bosonic keV-scale dark matter candidates of masses between 65 and 1021 keV has been performed with data collected during Phase II of the GERmanium Detector Array (Gerda) experiment. Our analysis includes direct dark matter …

An improved limit on the neutrinoless double-electron capture of $$^{36}$$Ar with GERDA

M. Agostini, A. Alexander, G. R. Araujo, A. M. Bakalyarov et autres

Abstract The GERmanium Detector Array (Gerda) experiment operated enriched high-purity germanium detectors in a liquid argon cryostat, which contains 0.33% of $$^{36}$$ 36 Ar, a candidate isotope for the two-neutrino double-electron capture (2 $$\nu $$ ν ECEC) and therefore for the neutrinoless …

Metal-Loaded Liquid Organic Scintillators for Recording Rare Events: Light Yield at High Metal Concentration

И. Р. Барабанов, A. Veresnikova, Z. Yu. Isupova, Б. В. Локшин et autres

Metal-loaded liquid organic scintillators (MeLS) are discussed from the point of view of light yield at high metal loading (Gd, Nd, Zr, In). It is shown that, when metal $$\beta$$ -diketonates are introduced into the scintillator, its light yield is always lower …
