We consider the cluster decay of 56Ni* formed in heavy-ion collisions, by using different parameters proposed by different authors for the Fermi density distribution and the nuclear radius. Our study reveals that different technical parameters do not alter significantly the structure of fractional yields. The cluster decay half-lives of different clusters lie within ±10% for different Fermi density parameters and nuclear radii and, therefore, justify the current set of parameters used in the literature for the calculation of cluster decays.

We study systematically the average property of fragmentation reaction and momentum dissipation induced by halo-nuclei in intermediate energy heavy ion collisions for different colliding systems and different beam energies within the isospin dependent quantum molecular dynamics model (IQMD). This study is based on the extended halo-nucleus density distributions, which indicates the average property of loosely inner halo nucleus structure, because the interaction potential and in-medium nucleon-nucleon cross section in IQMD model depend on the density distribution. In order to study the average properties of fragmentation reaction and momentum dissipation induced by halo-nuclei we also compare the results for the halo-nuclear colliding systems with those for corresponding stable colliding systems with same mass under the same incident channel condition. We find that the effect of extended halo density distribution on the fragment multiplicity and nuclear stopping (momentum dissipation) are important for the different beam energies and different colliding systems. For example the extended halo density distributions increase the fragment multiplicity but decrease the nuclear stopping for all of incident channel conditions in this paper.
