The search for resonant absorption of the Primakoff solar axions by 169Tm nuclei have been performed. Such an absorption should lead to the excitation of low-lying nuclear energy level: A + 169Tm → 169Tm* → 169Tm + γ (8.41 keV). The Si(Li) detector and 169Tm target placed inside the low-background setup were used for that purpose. As a result, a new restriction on the axion-photon coupling and axion mass was obtained: gA γ (GeV- 1) ṡ mA (eV) ≤ 1.36 × 10- 5 (90% c.l.). In model of hadronic axion this restriction corresponds to the upper limit on axion mass - mA ≤ 191 eV for 90% c.l.
