It is shown for the low-energy NN-bar interaction, within the framework of the coupled-channel scheme, that in the case of a small annihilation radius r/sub a/approx.m/sub N//sup ts-1/approx.0.2 F and strong attraction it is possible to obtain a consistent description of the small widths of the quasinuclear mesons (GAMMAapprox.10--30 MeV) and the large annihilation cross sections. The slow NN-bar annihilation cross section deviates in this case from the 1/v law. The character of the deviation depends on the potential NN-bar interaction.
