Abstract

Starting from a straightforward analogy with the absorption of gamma-rays in matter a simple model of high-energy nucleus-nucleus collisions is developed. Closed expressions for basic observables - the average number of interacting nucleons in a projectile nucleus (the number of „wounded nucleons“) and the dispersion of this number - are derived. Comparisons with experimental results for d-Ta, α-Ta and C-Ta collisions at 4.2 GeV/c per nucleon confirm the adequacy of the model and show that collisions develop predominantly as a sequence of independent nucleon-nucleon collisions.
