我们使用 EDELWEISS-II 实验的数据对轴子和更通用的类轴子粒子的耦合提出了新的约束。 EDELWEISS 实验位于 Modane 地下实验室，主要目的是使用锗辐射热测量计直接检测 WIMP。它还对太阳或暗物质轴子引起的低能电子反冲敏感。使用高达 448 kg.d 的总暴露量，我们在涉及轴子起源和耦合的不同假设的四种场景中搜索了低至 2.5 keV 的轴子引起的电子反冲。我们在轴子日光镜未完全覆盖的质量范围内对光子 $g_{A\gamma}<2.13\times 10^{-9}$ GeV$^{-1}$ 的耦合设置 95% CL 限制。我们还限制了与电子的耦合，$g_{Ae} < 2.56\times 10^{-11}$，类似于更间接的太阳中微子束缚。最后，我们对 $g_{Ae}\times g_{AN}^{\rm eff}<4.70 \times 10^{-17}$ 进行限制，其中 $g_{AN}^{\rm eff}$ 是 $^{57}$Fe 的有效轴子-核子耦合。结合这些结果，我们完全排除质量范围 $0.91\,{\rm eV}

We present new constraints on the couplings of axions and more generic axion-like particles using data from the EDELWEISS-II experiment. The EDELWEISS experiment, located at the Underground Laboratory of Modane, primarily aims at the direct detection of WIMPs using germanium bolometers. It is also sensitive to the low-energy electron recoils that would be induced by solar or dark matter axions. Using a total exposure of up to 448 kg.d, we searched for axion-induced electron recoils down to 2.5 keV within four scenarios involving different hypotheses on the origin and couplings of axions. We set a 95% CL limit on the coupling to photons $g_{A\gamma}<2.13\times 10^{-9}$ GeV$^{-1}$ in a mass range not fully covered by axion helioscopes. We also constrain the coupling to electrons, $g_{Ae} < 2.56\times 10^{-11}$, similar to the more indirect solar neutrino bound. Finally we place a limit on $g_{Ae}\times g_{AN}^{\rm eff}<4.70 \times 10^{-17}$, where $g_{AN}^{\rm eff}$ is the effective axion-nucleon coupling for $^{57}$Fe. Combining these results we fully exclude the mass range $0.91\,{\rm eV}
