Phys. Rev. C 75, 014604 (2007) [9 pages]Properties of the initial participant matter interaction zone in near-Fermi-energy heavy-ion collisionsReceived 13 March 2006; published 16 January 2007 The sizes, temperatures, and free neutron-to-proton ratios of the initial interaction zones produced in the collisions of 40 MeV/nucleon 40Ar+112Sn and 55 MeV/nucleon 27Al+124Sn are derived using total detected neutron plus charged particle multiplicity as a measure of the impact parameter range and number of participant nucleons. The size of the initial interaction zone, determined from a coalescence model analysis, increases significantly with decreasing impact parameter. The temperatures and free neutron-to-proton ratios in the interaction zones are relatively similar for different impact parameter ranges and evolve in a similar fashion. © 2007 The American Physical Society URL:
