New limit on axion-electron coupling obtained from searching for resonant absorption of solar axions by 83Kr nuclei

derbin_av@pnpi.nrcki.ru Abstract. A search for resonant excitation of first nuclear level of 83Kr nucleus at 9.4 keV by solar axion fluxes that depend on axion-electron coupling constant gAe have been performed. The search was carried out via gaseous proportional counter that was installed in a low -background experimental setup located at underground facility of Baksan Neutrino Observatory (INR RAS). The measurement yielded new limit on axion-electron coupling constant and axion mass |gAe mA| & LE; 1.33.10-9 eV.
