Abstract:

New theoretical calculations are performed to investigate the Coulomb proximity and angular momentum effects
on multifragmentation picture for 84Kr+112,124Sn collisions at an incident beam energy of 35MeV/nucleon.
Charge and isotopic distributions and the mean neutron-to-proton ratios of the fragments are reproduced within
the microcanonical Markov chain calculations on the basis of Statistical Multifragmentation Model. It is shown
that the Coulomb interactions and angular momentum e ects are very important to reproduce isotopic composition
of nuclear fragments in peripheral heavy-ion collisions at Fermi energies. Our results imply that it is
possible to investigate in laboratories the modification of structure parameters of fragments, such as the symmetry
energy coecient, at subnuclear densities in dense environment of other species.
