The search for solar axions produced by Compton ( \gamma + e ^ { - } \rightarrow e ^ { - } + A ) and bremsstrahlung-like ( e ^ { - } + Z \rightarrow Z + e ^ { - } + A ) processes has been performed .
The axion flux in the both cases depends on the axion-electron coupling constant .
The resonant excitation of low-lying nuclear level of ^ { 169 } Tm was looked for : A + ^ { 169 } Tm \rightarrow ^ { 169 } Tm ^ { * } \rightarrow ^ { 169 } Tm + \gamma ( 8.41 keV ) .
The Si ( Li ) detector and ^ { 169 } Tm target installed inside the low-background setup were used to detect 8.41 keV \gamma -rays .
As a result , a new model independent restriction on the axion-electron and the axion-nucleon couplings was obtained : g _ { Ae } \times|g ^ { 0 } _ { AN } + g ^ { 3 } _ { AN } | \leq 2.1 \times 10 ^ { -14 } .
In model of hadronic axion this restriction corresponds to the upper limit on the axion-electron coupling and on the axion mass g _ { Ae } \times m _ { A } \leq 3.1 \times 10 ^ { -7 } eV ( 90 % c.l . ) .
The limits on axion mass are m _ { A } \leq 105 eV and m _ { A } \leq 1.3 keV for DFSZ- and KSVZ-axion models , correspondingly ( 90 % c.l .
) .
