摘要：
We measured cross sections for production of antiprotons, K- and pi-mesons at theta(lab) = 0-degrees in nucleus-nucleus collisions for the systems Ne + NaF, Ne + Cu, Ne + Sn, Ne + Bi and for Ni + Ni, using Ne-20 and Ni-58 beams for the heavy ion synchrotron (SIS) at GSI with incident energies between 1.6 and 2.0 GeV/u. This energy range is far below the threshold for the production of antiprotons in free nucleon-nucleon collisions of 5.6GeV/u. The dependency on the incident energy, the size of the system and the momentum of the detected particle are discussed.
