Abstract

      A search for resonant absorption of the solar axions by Kr-83 nuclei was performed using the proportional counter installed inside the low-background setup at the Baksan Neutrino Observatory. The obtained model independent upper limits on axion-nucleon, - photon,- electron couplings are | g³_AN — g⁰_AN |≤8.4×10^-7 , | g_Aγ×m_A |≤6.3×10^-17, | g_Ae×m_A |≤1.4×10^-9 eV. The upper limit on axion mass is m_A ≤ 65 eV at 95% C.L. New experiment using resonant absorption of the solar axions by Fe-57 nuclei is proposed. Different materials containing Fe-57 which can be used as detectors working media are described.
