Search for axioelectric effect in Kr atoms for solar axions

A search for the axioelectric effect in krypton atoms for solar axions has been performed. The gaseous proportional chamber installed in a low- background setup located at underground facility of Baksan Neutrino Observatory (INR RAS) was used. As a result, new limits were obtained on the coupling constant of an axion with an electron $(|g_{Ae}|\le 4.9\cdot 10^{-11})$ and on the product of the coupling constant with an electron and a photon ($|g_{Ae}g_{A\gamma}|\le 1.6\cdot10^{-19}$ GeV$^{-1}$), all for 90% c.l.
