The nbar-Nucleus annihilation process has been studied by the OBELIX experiment at the CERN Low Energy Antiproton Ring (LEAR) in the (50-400) MeV/c projectile momentum range on C, Al, Cu, Ag, Sn and Pb nuclear targets. A systematic survey of the annihilation cross section has been performed, obtaining information on its dependence on the target mass number and on the nbar momentum. For the forst time the mass number dependence on the (inclusive) final state composition of the process has been analyzed. Production of the rho vector meson has also been examined.

Abstract
The nbar-Nucleus annihilation process has been studied by the OBELIX experiment at the CERN Low Energy Antiproton Ring (LEAR) in the (50-400) MeV/c projectile momentum range on C, Al, Cu, Ag, Sn and Pb nuclear targets. A systematic survey of the annihilation cross section has been performed, obtaining information on its dependence on the target mass number and on the nbar momentum. For the forst time the mass number dependence on the (inclusive) final state composition of the process has been analyzed. Production of the rho vector meson has also been examined.
