在这封信中，我们描述了我们用一束光子能量分别为50.2和90.7keV的X射线束，两个3T的超导磁体和一个高量子效率的Ge探测器进行的轴离子粒子搜索的新的光子再生实验。测量了与零兼容的再生光子的计数速率。得到了伪标量类轴子粒子-双光子耦合常数随粒子质量变化的相应极限。我们的装置通过耦合到两个光子，拓宽了致力于轴子类粒子搜索的纯地球实验的能量窗口。这也为光子在磁场中传播的实验研究开辟了新的领域。
In this Letter we describe our novel photon regeneration experiment for the axionlike particle search using an x-ray beam with a photon energy of 50.2 and 90.7 keV, two superconducting magnets of 3 T, and a Ge detector with a high quantum efficiency. A counting rate of regenerated photons compatible with zero has been measured. The corresponding limits on the pseudoscalar axionlike particle-two-photon coupling constant is obtained as a function of the particle mass. Our setup widens the energy window of purely terrestrial experiments devoted to the axionlike particle search by coupling to two photons. It also opens a new domain of experimental investigation of photon propagation in magnetic fields.
