Abstract
Abstract A search for resonant absorption of solar axions by $$^{169}\mathrm {Tm}$$ 169Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on $$\mathrm {Tm}_{3} \mathrm {Al}_{5} \mathrm {O}_{12}$$ Tm3Al5O12 crystal was used that allowed for significant improvement of sensitivity in comparison with previous $$^{169}\mathrm {Tm}$$ 169Tm based experiments. The measurements performed with 8.18 g crystal during 6.6 days exposure yielded the following limits on axion couplings: $$|g_{A\gamma } (g_{AN}^0 + g_{AN}^3) \le 1.44 \times 10^{-14}\,{{\mathrm{GeV}}^{-1}}$$ |gAγ(gAN0+gAN3)≤1.44×10-14GeV-1 and $$|g_{Ae} (g_{AN}^0 + g_{AN}^3) \le 2.81 \times 10^{-16}$$ |gAe(gAN0+gAN3)≤2.81×10-16 .
