We present new measurements of the energy spectra of cosmic-ray ( CR ) nuclei from the second flight of the balloon-borne experiment Cosmic Ray Energetics And Mass ( CREAM ) .
The instrument included different particle detectors to provide redundant charge identification and measure the energy of CRs up to several hundred TeV .
The measured individual energy spectra of C , O , Ne , Mg , Si , and Fe are presented up to \sim 10 ^ { 14 } eV .
The spectral shape looks nearly the same for these primary elements and it can be fitted to an E ^ { -2.66 \pm 0.04 } power law in energy .
Moreover , a new measurement of the absolute intensity of nitrogen in the 100-800 GeV/ n energy range with smaller errors than previous observations , clearly indicates a hardening of the spectrum at high energy .
The relative abundance of N/O at the top of the atmosphere is measured to be 0.080 \pm 0.025 ( stat . ) \pm 0.025 ( sys . )
at \sim 800 GeV/ n , in good agreement with a recent result from the first CREAM flight .
