Abstract

A search for axioelectric absorption of solar axions produced in the p + d → ³\rmHe+γ(5.5 \rmMeV) reactions has been performed with a BGO detector placed in a low-background setup. A model-independent limit on an axion-nucleon and axion-electron coupling constant has been obtained: | g_Ae× g_AN³|< 2.9× 10^-9 for 90% confidence level. The constrains of the axion-electron coupling have been obtained for hadronic axion with masses in (0.1 - 1) MeV range: |g_Ae| ≤ (1.4 - 9.7)× 10^-7.
