| 英文摘要 | The angular dependence of proton-proton correlation functions is studied in central Ca-40+Ca-40 and Ca-48+Ca-48 nuclear reactions at E/A = 80 MeV. Measurements were performed with the High Resolution Array (HiRA) complemented by the 4 pi Array at the National Superconducting Cyclotron Laboratory. A striking angular dependence in the laboratory frame is found within proton-proton correlation functions for both systems that greatly exceeds the measured and expected isospin dependent difference between the neutron-rich and neutron-deficient systems. Sources measured at backward angles reflect the participant zone of the reaction, while much larger sources observed at forward angles reflect the expanding, fragmenting, and evaporating projectile remnants. The decrease of the size of the source with increasing momentum is observed at backward angles while a weaker trend in the opposite direction is observed at forward angles. The results are compared to the theoretical calculations using the Boltzmann-Uehling-Uhlenbeck (BUU) transport model. |
