宇宙射线中的轻核和同位素丰度。结果来自AMS-01

Light Nuclei and Isotope Abundances in Cosmic Rays. Results from AMS-01

N. Tomassetti

摘要:

对轻宇宙射线核的化学和同位素组成的观测可以用来约束银河系中宇宙射线传输和相互作用的天体物理模型。AMS-01在1998年6月STS-91的10天飞行中观测到近200,000个轻核(Z>2)。利用这些数据,我们测量了轻核Li、Be、B和C在动能为0.35 - 45 GeV/核子范围内的相对丰度。

英文摘要:

Observations of the chemical and isotopic composition of light cosmic-ray nuclei can be used to constrain the astrophysical models of cosmic-ray transport and interactions in the Galaxy. Nearly 200,000 light nuclei (Z>2) have been observed by AMS-01 during the 10-day flight STS-91 in June 1998. Using these data, we have measured the relative abundance of light nuclei Li, Be, B and C in the kinetic energy range 0.35 - 45 GeV/nucleon.
