Phys. Rev. C 68, 034606 (2003) [18 pages]Coherent and incoherent giant dipole resonance γ-ray emission induced by heavy ion collisions: Study of the 40Ca+48Ca system by means of the constrained molecular dynamics modelReceived 31 July 2002; revised 13 March 2003; published 9 September 2003 Coherent and incoherent dipolar γ-ray emission is studied in a fully dynamical approach by means of the constrained molecular dynamics model. The study is focused on the system 40Ca+48Ca for which recently experimental data have been collected at 25 MeV/nucleon. The approach allows us to explain the experimental results in a self-consistent way without using statistical or hybrid models. Moreover, calculations performed at higher energy show interesting correlations between the fragment formation process, the degree of collectivity, and the coherence degree of the γ-ray emission process. © 2003 The American Physical Society URL:
