A multichannel M-matrix method is applied to the N[bar N] system, taking into account elastic p[bar p] scattering, charge exchange p[bar p][yields]n[bar n], and p[bar p] annihilation. In contrast to previous descriptions, the M-matrix elements are treated as real functions. the isospin breaking in the M matrix is taken into account. The authors describe the differential and total cross sections of p[bar p][yields]p[bar p] and p[bar p][yields]n[bar n], the cross section [sigma][sub tot] (p[bar p]), and the real-to-imaginary ratio of the forward amplitude of elastic p[bar p] scattering up to beam momenta p[sub lab] = 500 MeV/c and to bound states in the p wave near the p[bar p] threshold. 31 refs., 8 figs., 3 tabs.
