论文摘要
通过$^{169} $ tm核对太阳轴的谐振吸收进行了搜索。一种新开发的方法，该方法涉及基于TM $ _3 $ _3 $ _5 $ o $ o $ $ _ {12} $ Crystal的低背景低温验仪，与以前的$^{169} $ tm的实验相比，可以显着提高敏感性。在$ 6.6美元的暴露期间以$ 8.18 $ g的晶体执行的尺寸产生了以下限制：$ | g_ {aγ}（g_ {an}^0 + g_ {an}^3） （g_ {an}^0 + g_ {an}^3）\ leq 2.81 \ times 10^{ - 16} $。
A search for resonant absorption of solar axions by $^{169}$Tm nuclei was carried out. A newly developed approach involving low-background cryogenic bolometer based on Tm$_3$Al$_5$O$_{12}$ crystal was used that allowed for significant improvement of sensitivity in comparison with previous $^{169}$Tm based experiments. The measurements performed with $8.18$ g crystal during $6.6$ days exposure yielded the following limits on axion couplings: $|g_{Aγ} (g_{AN}^0 + g_{AN}^3) \leq 1.44 \times 10^{-14}$ GeV$^{-1}$ and $|g_{Ae} (g_{AN}^0 + g_{AN}^3) \leq 2.81 \times 10^{-16}$.
