The resonant excitation of the 83 Kr first excited nuclear level ( E = 9.4 keV) by solar axions whose fluxes depend on axion–electron coupling constant g Ae is sought. γ- and X-ray photons conversion Auger electrons from excited-level relaxation are detected with a gas proportional counter low-background detector in underground Baksan Neutrino Observatory (Institute for Nuclear Research, Russian Academy Sciences). As result, new constraint $${\text{|}}{{g}_{{Ae}}}(g_{{AN}}^{3} -...
Ultra-low-radioactivity titanium alloys are promising materials for the manufacture of low-background detectors which being developed experiments in astroparticle physics and neutrino astrophysics. Structural is manufactured on an industrial scale from sponge. The ultra-low-background sponge can be produced with a contamination level less than 1 mBq/kg uranium thorium isotopes. pathways contaminants during production structural were analyzed. measurements carried out using two methods:...
A search for resonant absorption of the solar axion by $^{83}\rm{Kr}$ nuclei was performed using proportional counter installed inside low-background setup at Baksan Neutrino Observatory. The obtained model independent upper limit on combination isoscalar and isovector axion-nucleon couplings $|g_3-g_0|\leq 8.4\times 10^{-7}$ allowed us to set new hadronic mass $m_{A}\leq 65$ eV (95\% C.L.) with generally accepted values $S$=0.5 $z$=0.56.

The obtained model independent upper limit on combination isoscalar and isovector axion-nucleon couplings $|g_3-g_0|\leq 1.69\times 10^{-6}$ allowed us to set new hadronic mass $m_{A}\leq 130$ eV (95\% C.L.) with generally accepted values $S$=0.5 $z$=0.56.
Abstract The study of low-yield effects requires not only good quality the original data but also puts high requirements for their processing procedures to increase efficiency selection useful events. exploiting large cylindrical proportional counter’s electrostatic topology allows improving extrapolation information about primary ionization a multipoint event. Long-term calibration measurements with an external 109 Cd-source allowed development new method analyzing pulse shape from sizeable...
We report on the study of thermal neutron flux using monitors based mixture ZnS(Ag) and LiF enriched with a lithium-6 isotope at deep underground laboratory DULB-4900 Baksan Neutrino Observatory. An annual modulation in is observed. Experimental evidences were obtained correlation between long-term variations absolute humidity air laboratory. The amplitude exceed 5\% total flux.
The results of investigation Xe-127 radioactive isotope production in the xenon sample enriched Xe-124, Xe-126, Xe-128 are presented. is supposed to be source background events low-background experiment on search for 2K-capture Xe-124. In this work we consider two channels production: neutron knock-out from nucleus by cosmogenic muons and capture Xe-126 nucleus. For first channel upper limit cross section was found sigma >= 0.007 barn at 95\% C.L. second value obtained equal =(2.74+-0.4)...
