In order to study the antiproton-nucleus potential (antimatter-mater potential), and prepare a possible experiment for the PANDA spectrometer at FAIR facility, we carried out a calculation with the Gießen-Boltzman-Uehling-Uhlenbeck(GiBUU) model.

The calculation was performed for an antiproton beam energy 1.5 GeV and an ¹⁶O target. The interesting events, which provide information about the antiproton-¹⁵N potential, are required to have one knocked-out proton in forward direction and two or more pions from the antiproton annihilation at rest. Preliminary results of these studies will be presented
