We study the multiplicity distribution of charged particles produced in 28-GeV/c pd interactions in the BNL 80-inch deuterium bubble chamber. We find that (18.3 +- 2.9) % of the three- and more-prong pd events result from double scattering in deuterium, a fraction observed to be constant from 28-to-400-GeV/c incident momentum. We extract pn topological cross sections from the odd-prong pd data by correcting for the effects of spectator visibility, double scattering, and Glauber screening. We find the dispersion of 28-to-400-GeV/c pd multiplicity distributions to have the same linear dependence on the mean multiplicity as found for pp data, while the pn data exhibit a different dependence. Both the pd and pn multiplicity distributions at 28 GeV/c are observed to be inconsistent with Koba-Nielsen-Olesen scaling.
