Collective clusterization in excited light nuclear systems

A new cluster decay process is proposed for the complex, intermediate mass fragments or clusters emitted in low energy nuclear reactions forming the excited light (A*(CN) similar to 60) and medium mass (A*(CN) similar to 110) nuclear systems. The complex fragments are shown to arise as multiple clusters of masses less than similar to20 in medium mass nuclei or as complete mass spectra in light nuclei. For Ba-116*, C-12 decay is still shown to be a preferred decay. The calculations for fragment production cross sections and total kinetic energies of fragments are presented for reactions leading to hot Ni-56 and Ba-116 nuclei.
