The cosmic-ray spectrum has an intensity enhancement in the energy range 10 14 –10 16 eV per nucleus 1 (Fig. 1). Recent observations of heavy cosmic rays in this energy range indicate that the Ca/Fe ratio may be as large as 10 times the solar value. We suggest that pulsars in type...
Measurements of cosmic rays in past decades have revealed a break around 1 PeV in the energy spectrum, which is called the "knee" of the cosmic ray energy spectrum due to its shape resembling a knee joint. However, the origin of cosmic rays in the "knee" region is still an unsolved mys...

The energy spectrum of cosmic-ray muons at sea-level is calculated by the numerical integration of a diffusion equation by assuming a scaling model. The calculated spectrum is in good agreement with the observed data of muons with the zenith angles of 0° and nearly 90°. Furthermore, by th...
