Abstract: The search for resonant absorption of Compton and bremsstrahlung solar axions by $^169$Tm nuclei have been performed. Such an absorption should lead to the excitation of low-lying nuclear energy level: $A + ^{169}Tm → ^{169}Tm^∗ → ^{169}Tm + γ$ (8.41 keV). Additionally the axio-electric effect in silicon atoms is sought. The axions are detected using a Si(Li) detectors placed in a low-background setup. As a result, a new model independent restrictions on the axion-electron and the axion-nucleon coupling: $g_{Ae} × |g^{0}_{AN} + g^{3}_{AN}| ≤ 2.1 × 10^{−14}$ and the axion-electron coupling constant: $|g_{Ae}| ≤ 2.2 × 10^{−10}$ has been obtained. The limits leads to the bounds$m_A ≤$ 7.9 eV and $m_A ≤$ 1.3 keV for the mass of the axion in the DFSZ and KSVZ models, respectively (90% C.L.).
