Abstract : 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 ¼ −0.333 + 0.014ðfitÞ + 0.005ðsystÞ, in good agreement with the
Kolmogorov theory of turbulence which predicts Δ ¼ −1=3 asymptotically.
