Abstract
Accurate measurements of the elemental composition of cosmic rays over a wide energy range are required in order to understand the origin, propagation and lifetime of the cosmic radiation. The primary cosmic rays (e.g. C and O), produced at the sources, propagate through the interstellar medium giving information about the composition at the source. Secondary elements (e.g. Li, Be, and B) are tracers of amount of matter traversed by the cosmic rays. PAMELA (Payload for Antimatter Matter Exploration and Light nuclei Astrophysics) is a satellite-borne experiment devoted to the study of the cosmic radiation over a wide energy range. The scientic objectives addressed by the mission are the measurement of the anti-protons and positrons spectra in cosmic rays, the hunt for anti-nuclei as well as the determination of light nuclei fluxes from hydrogen to oxygen in a wide energy range and with high statistics. New results on the boron and carbon spectra in the energy range 100 MeV/n - 100 GeV/n will be presented.
