Phys. Rev. C 75, 057601 (2007) [4 pages]Study of fragmentation at low excitation energies within a dynamical microscopic theoryReceived 22 November 2006; published 10 May 2007 We present the theoretical study of fragmentation at low excitation energies within dynamical microscopic theory namely, simulated annealing clusterization algorithm (SACA) and quantum molecular dynamics (QMD) model. For low excitation energy reactions, we choose the balance energies for a large number of reactions throughout the periodic table. We see that SACA gives multiplicities in terms of power law. For light fragments, it is close to 1/3, whereas, for heavier fragments it is nearly mass independent suggesting their origin in terms of participant-spectator picture. © 2007 The American Physical Society URL:
