Charged-particle multiplicity distributions in 300-GeV/c pd interactions have been determined from an exposure of the Fermi National Accelerator Laboratory 30-in. bubble chamber. The data show clear evidence for double scattering inside the deuterium nucleus. We have been able to correct for the effects of the second scatters using a simple semiempirical model. The resulting p p multiplicity distribution is in excellent agreement with the p p data obtained from a p-H2 experiment at the same energy. The p n multiplicity distribution appears to be shifted from the p p distribution with ncpn=7.84±0.17.
