The data on the production of charged and neutral particles are presented. It is found that the total cross section, the ..gamma.. cross section, and the K/sub s//sup 0/ cross section are 356 +- 13 mb., 3990 +- 550 mb., and 101 +- 11 mb., respectively. KNO scaling is observed in pNe interactions, but the KNO scaling function for the pNe interactions is a different not the same as the pp KNO scaling function. The R rapidity distribution (where R is the ratio of the number of particles produced in pNe and pp collisions) for the pions is found to peak at low rapidity and decrease to below 1 at high rapidity. Further, R is seen to be higher for ..pi../sup +/s than for ..pi../sup -/s in the central rapidity region. The correlation between pions is consistent with production of pairs of correlated pions, with no evidence for nucleus-wide pion condensation. The ..gamma..R distribution is consistent with the R distribution for pions. The K/sub s//sup 0/ R distribution peaks at low rapidity and falls off with increased rapidity as do the pion R distributions. However, the peak at low rapidity is seen to be higher and the slope of the distribution is seen to be steeper. Finally, the R distribution for the ..lambda..s is seen to peak in the central rapidity region, falling off with decreasing rapidity. The difference between the ..lambda.. results and the meson results is attributed to differences in the pp production of ..lambda..s and the mesons.
