The possibility of selecting the initial angular-momentum state from which antiproton-proton annihilation at rest can occur can be a fundamental tool in meson spectroscopy. With the OBELIX detector different target systems have been employed, ranging from S-wave to P-wave dominance. The preliminary results both on meson spectroscopy and branching ratio measurements are discussed.

Abstract
The possibility of selecting the initial angular-momentum state from which antiproton-proton annihilation at rest can occur can be a fundamental tool in meson spectroscopy. With the OBELIX detector different target systems have been employed, ranging from S-wave to P-wave dominance. The preliminary results both on meson spectroscopy and branching ratio measurements are discussed.
