【摘要】 用同位旋相关的量子分子动力学模型模拟了丰中子弹核引起(Be同位素)的核反应的中子-质子动量关联函数(即HBT),我们发现在小相对动量的中子-质子的HBT敏感于弹核的结合能,同时质子-晕中子的HBT依赖于核的单中子分离能.我们还研究了核态方程和介质中核子-核子截面的对HBT的影响.更多还原

【Abstract】 Hanbury Brown-Twiss (HBT) results of the nucleon-nucleon correlation function have been presented for the nuclear reactions with neutron-rich projectiles (Be isotopes) using an event-generator, the Isospin-Dependent Quantum Molecular Dynamics model. We explore that the relationship between the strength of the neutron-proton HBT at small relative momentum and the binding energy of the projectiles. Moreover, we reveal the relationship between the strength of the proton-halo neutron HBT and the single neutron separation energy. Results show that neutron-proton HBT results are sensitive to binding energy or separation energy. The dependences of Equation of State (EOS) and in-medium nucleon-nucleon cross section of the HBT results are also presented.更多还原
