使用 Soudan 2 探测器在 2090 mwe 深度的地下 μ 介子通量中观察到了统计显着性为 5{sigma} 的月球阴影。探测器的角分辨率可以用 sigma {<=}0.3 度符号的高斯函数很好地描述。阴影的位置证实探测器的对准已知优于 0.15 度符号，并且在十年的数据采集过程中保持稳定。 (c) 2000 年美国物理学会。
A shadow of the Moon, with a statistical significance of 5{sigma}, has been observed in the underground muon flux at a depth of 2090 mwe using the Soudan 2 detector. The angular resolution of the detector is well described by a Gaussian with a sigma {<=}0.3 degree sign . The position of the shadow confirms that the alignment of the detector is known to better than 0.15 degree sign and has remained stable during ten years of data taking.
