Abstract

We use computer simulations to study nuclear fragmentation as expected to occur in heavy ion reaction. Using integral equation techniques and molecular dynamics calculations we first find a potential with an equation of state resembling that of hot and dense nuclear matter. We then use this potential to study the disassembly of two dimensional classical drops. Along the lines of Cahn's theory of spinodal decomposition we calculate the structure factor of the system and extract information about the development of density fluctuations during the breakup. We find isothermal spinodal decomposition to play the dominant role in the breakup. Nucleation of bubbles in the two phase region and adiabatic spinodal decomposition were found not to contribute to the fragment production. Strong density fluctuations were detected in disassemblies crossing the critical point.
