| 英文摘要 | Present experiment was performed in order to get more information about intermediate energy heavy ion collisions for the further understanding of that how nuclear reaction mechanisms change between the two extreme types of nuclear behaviors, the nuclear collisions at low and high energy. Ba isotopes were produced by 60 MeV/u O-18 bombardment of nature uranium via U-238(O-18, X) reaction, and then separated from the irradiated U targets by using radiochemical procedure. The accumulative sections of Ba isotopes are obtained through the processing and analyzing of time sequence gamma-ray spectra. As a result, the two-peak phenomenon in the distribution of the Ba isotopes is observed. It can be presumed that the occurrence of the double Gaussian distribution is weakly related to the projectile energy, but closely related to the projectile-target combination. Present experiment also implied however, that fragmentation reaction induced by intermediate energy heavy ions followed by radiochemical separation is an efficacious method to produce nuclei far from stability, thereby to study their decay properties. |
