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 | g3AN — g0AN |≤8.4×10-7 , | g×mA |≤6.3×10-17, | gAe×mA |≤1.4×10-9 eV. The upper limit on axion mass is mA ≤ 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.
