利用BESS谱仪精确测量了不同地磁位置的大气μ子垂直绝对通量和μ子电荷比。观测是在日本筑波的海平面（海拔30米）和加拿大林恩湖海拔360米处进行的。筑波（36.2 ° N，140.1 ° E）和林恩湖（56.5 ° N，101.0 ° W）的垂直截止刚度分别为11.4和0.4 GV。在动量为0.6 ~ 20 GeV/c的范围内，我们得到了正负μ子的垂直通量
The vertical absolute fluxes of atmospheric muons and muon charge ratio have been measured precisely at different geomagnetic locations by using the BESS spectrometer. The observations had been performed at sea level (30 m above sea level) in Tsukuba, Japan, and at 360 m above sea level in Lynn Lake, Canada. The vertical cutoff rigidities in Tsukuba (36.2degreesN, 140.1degreesE) and in Lynn Lake (56.5degreesN, 101.0degreesW) are 11.4 and 0.4 GV, respectively. We have obtained vertical fluxes of positive and negative muons in a momentum range from 0.6 to 20 GeV/c with systematic errors
