We searched for resonant excitation of the first excited state of the 169Tm nucleus by axions formed inside the Sun by the Primakoff effect, A + 169Tm → 169Tm* → 169Tm + γ (8.41keV). Gamma quanta with an energy of 8.41keV were registered by a sectionalized Si(Li) detector installed in a low-background setup. As a result, we set a new upper limit for the photon to axion coupling constant, gAγ(GeV-1)mA(eV) ≤ 1.06 × 10-5, which for a hadronic axion model corresponds to a mass limit of mA ≤ 169 eV at a 90% confidence level.
