摘要:

利用大视场切伦科夫望远镜和ARGO-YBJ实验的电阻板室(RPC)阵列的混合实验,在海拔4300米处测量了宇宙氢和氦核的能谱,低于所谓的“膝盖”。利用多参数技术,氢核和氦核与宇宙线的其他成分已被很好地分离。在整个能量范围(100 TeV - 700 TeV)内实现了约25%的高度均匀的能量分辨率。观测到的能谱符合指数γ =-2.63+/-0.06的单一幂律。

英文摘要:

The energy spectrum of cosmic Hydrogen and Helium nuclei has been measured, below the so-called "knee", by using a hybrid experiment with a wide field-of-view Cherenkov telescope and the Resistive Plate Chamber (RPC) array of the ARGO-YBJ experiment at 4300 m above sea level. The Hydrogen and Helium nuclei have been well separated from other cosmic ray components by using a multi-parameter technique. A highly uniform energy resolution of about 25% is achieved throughout the whole energy range (100 TeV - 700 TeV). The observed energy spectrum is compatible with a single power law with index gamma=-2.63+/-0.06.
