Description
We present a measurement of subthreshold antiproton, kaon, and energetic pion production at 0 degree for the reactions 28Si+28Si at 2.0 GeV/nucleon (Eavailable/A=0.82 GeV) and 1.65 GeV/nucleon (Eavailable/A=0.70 GeV), and for 20Ne+NaF at 2.0 GeV/nucleon. For a given reaction, the particle yields, plotted as a function of the required excitation energy, exhibit a scaling behavior independent of particle species. Implications for collectivity and a common production mechanism are discussed
