Abstract
The results of the measurements of antiproton-nuclei annihilation cros s-sections at the momentum range from 0.70 to 2.50 GeV/c are presented . The A-dependence of the cross-sections is described by the formula s igma(0)A(alpha). The behavior of the parameters sigma(0) and alpha ind icates the possibility of Coulomb influence on the annihilation proces ses at low momenta. Comparison with the Glauber theory is carried out. The Coulomb corrections to the Glauber formula for the absorption cro ss-sections of hadrons by nuclei are calculated. The influence of the real part of the nuclear potential is taken into account. Calculations are made in the frame of the high-energy approach. A comparison with data of annihilation cross-sections of antiprotons on nuclei is made.
