Abstract:	Isospin effects in 12C ion induced reactions on enriched tin isotopes are investigated. The isoscaling parameter B is determined for different mass regions of product nuclei. Isospin effect is also discussed for deuterons and protons with different initial energies. It is shown that the isoscaling parameter is sensitive to the formation mechanism of products, and increases as the difference in the asymmetry is increasing. Mean values of symmetry energy coefficient gamma of about 13 MeV for proton-induced reactions and 12 MeV for deuteron-induced reactions are determined for different mass regions of product nuclei which conform the central character of collisions.
