Vf. Kuzichev et al., THE ANTIPROTON-NUCLEI ANNIHILATION CROSS-SECTION AT THE MOMENTUM RANGE FROM 0.70-GEV C TO 2.50-GEV/C/, Nuclear physics. A, 576(4), 1994, pp. 581-602
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.
