“…The 7 Be electron capture also produces neutrinos with a flux equal to 4.8 × 10 9 (±10%)ν/(cm 2 s) at the Earth [31]. The expected flux of axions is directly related to the total flux of 7 Be neutrino and is comparable with axion flux in experiments using nuclear reactors [32] or artificial radioactive sources [33] (see [5] and refs. therein).…”

Abstract. Results of background measurements with a prototype of the Borexino detector were used to search for 478 keV solar axions emitted in the M1-transitions of 7 Li * . The Compton conversion of axion to a photon A + e → e + γ, axioelectric effect A + e + Z → e + Z, decay of axion in two photons A → 2γ and Primakoff conversion on nuclei A + Z → γ + Z are considered. The upper limit on constants of interaction of axion with electrons, photons and nucleons -g Ae g AN ≤ (1.0-2.4) × 10 −10 at m A ≤ 450 keV and g Aγ g AN ≤ 5 × 10 −9 GeV −1 at m A ≤ 10 keV are obtained (90%c.l.). For heavy axions with mass at 100 < m A < 400 keV the limits g Ae < (0.7-2.0) × 10 −8 and g Aγ < 10 −9 -10 −8 are obtained in assumption that g AN depends on m A as for KSVZ axion model. These limits are stronger than obtained in previous laboratory-based experiments using nuclear reactor and artificial radioactive sources.

Search for axions from the Kuo-Sheng nuclear power reactor with a high-purity germanium detector

A search of axions produced in nuclear transitions was performed at the Kuo-Sheng Nuclear Power Station with a high-purity germanium detector of mass 1.06 kg at a distance of 28 m from the 2.9 GW reactor core. The expected experimental signatures were mono-energetic lines produced by their Primakoff or Compton conversions at the detector. Based on 459.0/96.3 days of Reactor ON/OFF data, no evidence of axion emissions were observed and constraints on the couplings gaγγ and gaee versus axion mass ma within the framework of invisible axion models were placed. The KSVZ and DFSZ models can be excluded for 10 4 eV ma 10 6 eV. Model-independent constraints on gaγγ · g 1 aNN < 7.7 × 10 −9 GeV −2 for ma 10 5 eV and gaee · g 1 aNN < 1.3 × 10 −10 for ma 10 6 eV at 90% confidence level were derived. This experimental approach provides a unique probe for axion mass at the keV−MeV range not accessible to the other techniques.

This article reports the first study of possible emissions of axions from power reactors using Primakoff and Compton conversions as the detection mechanisms. The experiment was performed at the Kuo-Sheng (KS) Nuclear Power Station with a high-purity germanium detector of mass 1.06 kg at a distance of 28 m from the 2.9 GW reactor core. The expected experimental signatures are mono-energetic lines produced by Primakoff or Compton conversions of axions at the detector. Based on 459.0/96.3 days of reactor ON/OFF data, no evidence of axion emission was observed and constraints on axion couplings g aγγ and g aee versus axion mass m a within the framework of invisible axion models were placed. The KSVZ and DFSZ models can be excluded for 10 4 eV m a 10 6 eV. Model-independent constrains on g aγγ · g 1 aNN < 7.7 × 10 −9 GeV −2 for m a 10 5 eV and g aee · g 1 aNN < 1.3 × 10 −10 for m a 10 6 eV at 90% confidence level were derived. This experimental approach provides a unique probe for axion mass at the keV-MeV range not accessible to the other techniques. Identification of dark matter
