Abstract：
Based on a transport equation of the Fokker-Planck type the correlations in theangular-momentum distributions of binary fragments in deeply inelastic heavy-ion col-lisions are investigated. A strong anticorrelation is found due to the centrifugal part ofthe driving potential. The correlation angle increases towards mass symmetry andreaches 45° for symmetric fragmentation.
