    "abstract": "The excitation energy and the nuclear density at the time of breakup are\nextracted for the $\\alpha + ^{197}Au$ reaction at beam energies of 1 and 3.6\nGeV/nucleon. These quantities are calculated from the average relative velocity\nof intermediate mass fragments (IMF) at large correlation angles as a function\nof the multiplicity of IMFs using a statistical model coupled with many-body\nCoulomb trajectory calculations. The Coulomb component $\\vec{v}_{c}$ and\nthermal component $\\vec{v}_{0}$ are found to depend oppositely on the\nexcitation energy, IMFs multiplicity, and freeze-out density. These\ndependencies allow the determination of both the volume and the mean excitation\nenergy at the time of breakup. It is found that the volume remained constant as\nthe beam energy was increased, with a breakup density of about $\\rho_{0}/7$,\nbut that the excitation energy increased $25\\%$ to about 5.5 MeV/nucleon.",
