Abstract
We have carried out a set of Monte Carlo calculations of the transport of cosmic-ray nuclei in the Galaxy. These calculations are used to examine the effect of the cosmic-ray source distribution on the matter path length distribution traversed by cosmic rays in the Galaxy. A comparison of cosmic-ray data with calculations using a simple leaky-box propagation model has earlier suggested that this matter distribution is close to an exponential, with a possible depletion of short path lengths at low energies. Such an effect could be caused by either a nonuniform source distribution or nonuniform propagation conditions
