Investigation of +Ne and -Ne interactions at 10.5 GeV/c

Detailed studies of +Ne and -Ne interactions at 10.5 GeV/c have been carried out. Multiplicities, correlations, and inclusive momentum and rapidity spectra for +, -, 0, and p are reported. Average multiplicities for K0 and 0 production are also determined. Comparisons are made to results from p interactions. Relative to 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 1.3 GeV/c). For shower-track multiplicities 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. © 1977 The American Physical Society.
