N2 - We measured cross sections for the subthreshold production of antiprotons and K- mesons in nucleus-nucleus collisions for the systems Ne+NaF, Cu, Sn, and Bi, and recently also Ni+Ni, using 20Ne and 58Ni beams from the heavy ion synchrotron (SIS) at GSI with energies between 1.6 GeV/u and 2.0 GeV/u. π- production cross sections were also determined. The dependency of the measured cross sections on the incident energy, the size of the system and the momentum of the detected particle is discussed.
