| 英文摘要 | Isotope ratios,defined as the yield ratio of two isotopes with the same charge,were analyzed as a function of kinetic energy of outgoing particles at 20 degrees in the reactions of Ar-40 + Sn-112.124 and 5 degrees in Ar-36 + Sn-112.124 at incident energy of 35MeV/u. Isotope ratios between the neutron-deficient isotopes and stable isotope increase with kinetic energy,while those between the neutron-rich isotopes and stable isotope decrease. This different behavior was observed similar for both Sn-112 and Sn-124 targets. The isotope ratios show rather obvious target dependence at 20 degrees and little target dependence at 5 degrees. As the outgoing energy getting down, the N/Z ratio of the fragmentation products at 5 degrees diverts gradually from the N/Z ratio of the projectile to that of the system. These observations indicate that the isospin degree of freedom does not reach complete equilibrium in the peripheral or semi-peripheral collision at this bombarding energy. |
