Multifragmentation, following the formation of toroidal and bubble nuclei, is observed with an improved Boltzmann-Uehling-Uhlenbeck (BUU) model for central [sup 92]Mo [plus] [sup 92]Mo collisions. Guided by our BUU model, we propose two signatures: (1) because of the geometries of bubbles and toroids and because of the cold breakup at low temperatures, we predict enhanced cross sections for fragments with nearly-equal masses at small center-of-mass energies. (2) the coplanarity of these nearly-equal fragments could carry important information concerning the geometry of the sources. This in turn, could provide information about the stiffness of the equation of state.
