N2 - The exact expressions for scattering length and partial total cross-section for pn and pp systems are obtained in the frame of the extended Hubert space model with continuous spectrum of resonances treated as an annihilation channel. The numerical algorithm for scattering data calculation is suggested. The numerical calculations for p̄n and p̄p scattering data at angular momentum L = 0,1,2,3 are performed on this base. The interaction parameters are fitted via two-body scattering data. A satisfactory agreement between experimental and theoretical data is obtained.
