The production of energetic π− at 0° has been measured in Ne+NaF and Ni+Ni collisions with incident energies between 1.3 and 2AGeV. In Ne+NaF collisions the investigation was extended to extreme subthreshold processes with lab momenta up to 4.5 GeV/c. In both systems at all incident energies the π− production cross sections deviate in a systematic way from thermal distributions.

Inclusive Cross-Sections for 180-Degree Production of High-Energy Protons, Deuterons, and Tritons in p-Nucleus Collisions at 600-MeV and 800-MeV

The inclusive cross sections, measured up to large values of effective mass (≡q22ν), are well fitted by dσd3p=Bxexp(−αxp22mx). Values of Bx and αx are given for Be, C, Cu, and Ta at the incident proton energy of 600 MeV and for Ag, Ta, and Pt at 800 MeV. Extremely large dp and tp ratios and large A and q2 dependences of the relative cross sections are observed.
