在德国汉堡的Kiel-Desy团队测量了约6× 10.5 μ子在天顶角θ= 68 ~ 82和能量E= 1 ~ 1000 GeV范围内的光谱。数据用一个简单的拟合形式表示，在非常高的能量下，积分谱的拟合形式为E−2.57 sec θ。表明银河宇宙射线核子谱在1000 GeV以上比E - 2.75更平坦。
The spectrum of about 6× 10 5 muons in the zenith angle range θ= 68− 82 and the energy range E= 1− 1000 GeV has been measured by a Kiel-Desy collaboration at Hamburg. The data are represented by a simple form fit which goes as E− 2.57 sec θ for the integral spectrum at very high energies. indicating that the galactic cosmic-ray nucleon spectrum is flatter than E− 2.75 beyond 1000 GeV.
