We measure cross sections for residual nuclide formation in the mass range 6
< A < 97 caused by bombardment with protons and deuterons of 3.65 GeV/nucleon
energy of enriched tin isotopes (112-Sn, 118-Sn, 120-Sn, 124-Sn). The
experimental data are compared with calculations by the codes FLUKA, LAHET,
CEM03, and LAQGSM03. Scaling behavior is observed for the whole mass region of
residual nuclei, showing a possible multifragmentation mechanism for the
formation of light products (6 < A < 31). Our analysis of the isoscaling
dependence also shows a possible contribution of multifragmentation to the
production of heavier nuclides, in the mass region 39 < A < 81.
