General features of total hadron-nucleus reaction cross sections

Total reaction cross sections for many hadronic projectiles (π+, π-, n, p, anti p, K+, K-, anti d) and bombarding energies (200 MeV to 300 GeV) on several target nuclei are compiled. Two remarkable features are discussed: (1) the average systematic behaviour of data is well reproduced by the Glauber model, containing only the free projectile-nucleon total cross section sigma; (2) deviations of the cross section data from an average smooth dependence on sigma seem to vary periodically with sigma-1, independent of the projectile type and of the target nucleus.
