摘要

Recent accurate measurements of the cosmic-ray (CR) proton, helium, and heavier nuclei by ATIC-2,CREAM, and PAMELA reveal: a) unexpected hardening in the spectra of CR species above a few hundred GeV pernucleon, b) a harder spectrum of He compared to protons, and c) softening of CR spectra just below the break energy (a'dip'). These features may offer a clue to the origin of the observed high-energy Galactic CRs. We discuss possible inter-pretationsof these spectral features and make predictions of the diffuse Galactic -ray emission, CR isotopic ratios, andanisotropy of CRs for different scenarios. Our predictions can be tested by currently running or near-future high-energyastrophysics experiments.
