We present new measurements of the
energy spectra of cosmic-ray (CR) nuclei from
the second flight of the balloon-borne experiment
CREAM (Cosmic Ray Energetics And Mass). The
instrument (CREAM-II) was comprised of detectors
based on different techniques (Cherenkov light, specific
ionization in scintillators and silicon sensors)
to provide a redundant charge identification and a
thin ionization calorimeter capable of measuring the
energy of cosmic rays up to several hundreds of TeV.
The data analysis is described and the individual
energy spectra of C, O, Ne, Mg, Si and Fe are
reported up to 1014 eV. The spectral shape looks
nearly the same for all the primary elements and can
be expressed as a power law in energy E−2.66±0.04.
The nitrogen absolute intensity in the energy range
100-800 GeV/n is also measured
