Detailed studies of ..pi../sup +/Ne and ..pi../sup -/Ne interactions at 10.5 GeV/c have been carried out. Multiplicities, correlations, and inclusive momentum and rapidity spectra for ..pi../sup +/, ..pi../sup -/, ..pi../sup 0/, and p are reported. Average multiplicities for K/sup 0/ and ..lambda../sup 0/ production are also determined. Comparisons are made to results from ..pi..p interactions. Relative to ..pi..p collisions, pion production is enhanced in the target-fragmentation region but not in the central or projectile-fragmentation regions. Many of the pion production properties can be understood in terms of a simple kinematical model in which the effective target mass is greater than a nucleon mass. A surprising number of energetic protons are observed (laboratory momentum > or approx. = 1.3 GeV/c). For shower-track multiplicities approx.8, the produced nucleons are found to carry away an average of 40% of the incident momentum, indicating the possible existence of previously unrecognized mechanisms for the efficient momentum transfer to nucleons in particle-nucleus collisions.
