Abstract:	摘要： Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B/C ratio from 1.9 GV to 2.6 TV, based on 2.3 million boron and 8.3 million carbon nuclei collected by AMS during the first 5 years of operation, is presented. The detailed variation with rigidity of the B/C spectral index is reported for the first time. The B/C ratio does not show any significant structures in contrast to many cosmic ray models that require such structures at high rigidities. Remarkably, above 65 GV, the B/C ratio is well described by a single power law RΔ with index Δ=-0.333±0.014(fit)±0.005(syst), in good agreement with the Kolmogorov theory of turbulence which predicts Δ=-1/3 asymptotically. 其他題名： Phys Rev Lett 出版者： United States: American Physical Society 出版日期： 2016-12-02 出處： Physical review letters, 2016-12, Vol.117 (23), p.231102, Article 231102 資源來源： American Physical Society Journals 版權： licence_http://creativecommons.org/publicdomain/zero 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： ISSN: 1092-0145 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/PhysRevLett.117.231102 識別號： PMID: 27982618
