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 pp multiplicity distribution is in excellent agreement with the pp data obtained from a p-H₂ experiment at the same energy. The pn multiplicity distribution appears to be shifted from the pp distribution with $$\langle$$nc$$\rangle$$ _pn=7.84±0.17.
