Total cross sections for π − , K − and p on protons and deutrons have been measured in the momentum range 15 to 60 GeV/ c . Total cross sections for particle interactions with neutrons have been determined with an energy dependent Glauber correction. Using the positive particle data obtained earlier with the same experimental apparatus, the differences of total cross sections for particles and antiparticles as well as for particles belonging to the same isospin multiplet have been calculated.

From the energy dependence of the p¯p and p¯n inelastic cross sections we deduce an upper limit to the resonant contribution in p¯p backward scattering for c.m. energies between 1915 and 1950 MeV. This limit is smaller than the expected contribution from diffraction scattering. The energy dependence of the 180° p¯p elastic cross section in this energy range cannot therefore be directly related to the formation of s-channel resonances.
CROSS SECTION ONLY FOR ANNIHILATION EVENTS WITH EMISSION OF SPECTATOR PROTON TOO SLOW TO GIVE A VISIBLE TRACK (LESS THAN ABOUT 80 MEV/C) - ABOUT 60 PCT OF TOTAL ANNILILATION. NUMERICAL VALUES TAKEN FROM TABLE 2 OF R. BIZZARRI ET AL., NC 22A, 225 (1974).
We have measured the p¯n differential elastic cross section for −t≥0.15 (GeV/c)2. We compare our data with existing data from p¯p and np elastic scattering experiments in this energy region. Our data show a dip in the cross section at −t≃0.45 (GeV/c)2 and a secondary maximum at −t≃0.7 (GeV/c)2. We see no evidence for backward peaking in p¯n elastic scattering at this energy. Evidence is presented for I=1, t-channel exchange in N¯N scattering.
