title = "Observation of the Identical Rigidity Dependence of He, C, and O Cosmic Rays at High Rigidities by the Alpha Magnetic Spectrometer on the International Space Station",
abstract = "We report the observation of new properties of primary cosmic rays He, C, and O measured in the rigidity (momentum/charge) range 2 GV to 3 TV with 90×106 helium, 8.4×106 carbon, and 7.0×106 oxygen nuclei collected by the Alpha Magnetic Spectrometer (AMS) during the first five years of operation. Above 60 GV, these three spectra have identical rigidity dependence. They all deviate from a single power law above 200 GV and harden in an identical way.",

note = "Funding Information: We thank former NASA Administrator Daniel S. Goldin for his sustained support of the ISS as a scientific laboratory and his decision for NASA to fly AMS as a DOE payload. We also acknowledge the continuous support of the NASA leadership, including Charles Bolden and William H. Gerstenmaier and of the JSC and MSFC flight control teams, which has allowed the AMS to operate optimally on the ISS for over six years. We are grateful for the support of Jim Siegrist and his staff of the DOE, including resources from the National Energy Research Scientific Computing Center under Contract No. DE-AC02-05CH11231.
