Here we perform a systematic study to extract the information for colliding nuclear matter via symmetry energy and nucleon-nucleon cross section in the fragmentation of some asymmetric colliding nuclei (O{sup 16}+Br{sup 80,} {sup 84,} {sup 92}) in the energy range between 50-200 MeV/nucleon. The simulations are carried out using isospin-dependent quantum-molecular dynamics (IQMD) computational approach for central collisions. Our study reveals that fragmentation pattern of neutron-rich colliding nuclei is sensitive to symmetry energy at lower incident energies, whereas isospin dependence of nucleon-nucleon cross section becomes dominant for reactions at higher incident energies.
