Abstract: Kinematic correlations between three heavy projectile fragments produced in Au induced reactions at E/A = 600 MeV are presented. The sensitivity of these correlations to the disassembly geometry is confirmed by classical three-body trajectory calculations. The simulation suggest a fast disintegration process of an highly excited system. Withn the assumed scenarios the data constrain a possibly existing radial flow to a maximum value of about 1 MeV per nucleon. This radial motion can be provided by the Couomb repulsion between the fragments if the breakup occurs out of a volume with a radius not larger than 15 fm.
