摘要：

K+ and pi+ multiplicities have been measured in a magnetic spectrometer for Si+Al, Si+Cu and Si+Au collisions at 14.6 A GeV/c incident momentum. The multiplicities were obtained for rive different windows of forward kinetic energy as detected in a zero degree calorimeter. The K+/pi+ multiplicity ratio ranges from almost-equal-to 9% in peripheral interactions to 19% in central Si+Au. The largest K+/pi+ ratios are observed for those events for each target that leave the least energy in the zero degree calorimeter and the ratio increases with target mass. The observations suggest that multiple interactions are important in the particle production mechanism.
