摘要：

First results concerning p-pBAR and n-pBAR annihilation cross section and n-pBAR total cross sections at low energies (2.25 less-than-or-equal-to E(pBAR) less-than-or-equal-to 2.76 MeV and 3.4 < E(nBAR) < 44.6 MeV) 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.
