Abstract
It is shown that the mechanism of low-energy antiproton scattering from nuclei is given by the Glauber model including Coulomb effects. The cross sections for elastic and inelastic (with excitation of nuclear level) p scattering from 12C and 16O and also for elastic scattering from 40Ca and 208Pb are calculated without any free parameters. Calculations are in good agreement with LEAR data. The real-to-imaginary ratios of the p N scattering amplitude are found from antiprotonnucleus cross sections at diffractive minima at energies of 46.8 and 179.7 MeV, which also agree with LEAR values of this ratio. The antiproton-nucleus optical potential and scattering lengths are calculated. Shifts of the 3d levels of the antiproton atoms p 12 C and p 16 O are estimated and are found to be in good agreement with experiment.
