摘      要：In this report,a kinematical focusing technique will be briefly described,and using this technique,the primary hot isotope yields from the multiplicities of evaporated light particles,associated with isotopically identified intermediate mass fragments,are *** energy and characteristic properties of the fragmenting source at the time of the intermediate mass fragment formation are extracted from these reconstructed primary isotope yields using a self-consistent *** extracted density-dependent symmetry energy is further compared with those experimentally extracted from other heavy-ion reactions in literatures.A direct connection between the freeze-out concept and transport model simulations in a multifragmenting regime of heavy-ion collisions is also demonstrated quantitatively in the present work.
