A search for resonant absorption of solar axions by 
nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on 
crystal was used that allowed for significant improvement of sensitivity in comparison with previous based experiments. The measurements performed with 8.18 g crystal during 6.6 days exposure yielded the following limits on axion couplings: 
and
