  A new, sensitive method allows one to search for the enhancement of events
with nearly equal-sized fragments as predicted by theoretical calculations
based on volume or surface instabilities. Simulations have been performed to
investigate the sensitivity of the procedure. Experimentally, charge
correlations of intermediate mass fragments emitted from heavy ion reactions at
intermediate energies have been studied. No evidence for a preferred breakup
into equal-sized fragments has been found.
