FLUCTUATION DYNAMICS OF FRAGMENTING SPHERICAL NUCLEI

We use the quasiclassical nuclear model and the recently proposed earl y cluster recognition algorithm to investigate the dynamical evolution of the fragmentation pattern for suitably excited finite spherical sp in-isospin symmetric system of 80 nucleons. We find that the asymptoti c fragment structure (when clusters are far away from each other) is s trongly related to the early most bound density fluctuations (MBDF's) in phase space (when the system is dense). We focus on the evolution o f the microscopic structure of this MBDF, finding that the constituent s of the MBDF are strongly correlated in time. Our calculations indica te that not only the final fragment spectra but also the microscopic s tructure of the final clusters carry information about the early stage s of the evolution.
