Cluster emission from highly excited nuclei which are formed in heavy ion collisions is investigated within di-nuclear system model(DNS). Depending on entrance channel mass asymmetry and on energy of projectile, one can form highly excited compound nucleus(CN) with different angular momentums. Competition of different channels such as light particle emission(neutrons, protons and etc), complex fragment(cluster) emission and fission, depend on the angular momentum of the intermediate system. Here we present the results for cluster emission cross sections and isotopic distribution of these clusters for different reactions with different angular momentum and excitation energy
