英文摘要	Coincidence measurements between residues and light charged particles ( LCPs) have been made for the reactions 30MeV/u Ar-40 + Sn-112,Sn-124. The LCPs were measured by 11 semi-conduct telescopes from very forward angle to backward angle. The times of flight of the, residues were measured by PPACs installed concentrically around the beam at forward angle. The excitation energy of the primary hot nuclei was obtained from the velocity of residues in the frame of incomplete fusion model. The single isotope ratios, as function of observing angle and excitation energy have been studied. The ratio of He-3/He-4 and Li-6/Li-7 increases with angle while that of He-6/He-4 and Li-8/Li-7 decreases. The calculation of statistical theory can not reproduce the curve quantitatively, implying the existence of dynamic effect. Isospin effect of the primary hot nuclei on the single isotopic ratios is demonstrated. However, the temperature extracted from double isotope ratios is target independent.
