Abstract

First results concerning -p and -p annihilation cross section and -p total cross sections at low energies () obtained by the OBELIX spectrometer are reported. The agreement with the few existing data in this energy range is good; the comparison with some models gives interesting indications on the S and P wave contribution at very low energy and on the range of the elastic interaction.
