我们报告宇宙射线质子和氦谱的能量范围为1-120 GeV的核子-1和1-54 GeV的核子-1，分别由一个飞行的超导谱仪（BESS）在1998年测量的。通过对1 T均匀螺线管磁场中的圆形轨迹的高精度测量，可靠地确定了宇宙线的磁刚度。这些光谱在质子的±5%和氦核的±10%的总体不确定度内确定，包括统计和系统误差。
We report cosmic-ray proton and helium spectra in energy ranges of 1-120 GeV nucleon-1 and 1-54 GeV nucleon-1, respectively, measured by a flight of the Balloon-borne Experiment with Superconducting Spectrometer (BESS) in 1998. The magnetic rigidity of the cosmic ray was reliably determined by highly precise measurement of the circular track in a uniform solenoidal magnetic field of 1 T. Those spectra were determined within overall uncertainties of ±5% for protons and ±10% for helium nuclei including statistical and systematic errors.
