With use of the east-west asymmetry effect of arriving cosmic-ray primaries, we can obtain the energy spectra for individual elements in the kinetic energy range from a few GeV/nucleon up to∿15GeV/nucleon. We present also the energy spectra obtained by the opening-angle method for the higher energy region, 5∿1000GeV/nucleon, for the elements not lighter than silicon. We find that the energy spectra obtained by the former method continue smoothly to those obtained by the latter, indicating that the energy determination using the opening-angle method is performed correctly. We compare also the present results with those obtained by the previous work. We find that the iron flux is in nice agreement with that obtained by the previous observation, the differential spectral index being constant, ∿2.5,up to a few TeV/nucleon, while in the case of silicon component, it is ∿2.7 for 10∿1000GeV/nucleon in this work, significantly harder than the previous one, ∿2.9. We also report the flux of the sub-iron component and its abundance ratio to the iron component. We find the abundance ratio of [Z=21-25]/iron is slightly less than those obtained previously in the higher energy region, ≳100GeV/nucleon.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
