采用同位旋相关的量子分子动力学模型(Isospin-Dependent Quantum Molecular Dynamics model,IDQMD),把HBT方法应用于核物质的性质研究.计算结果显示,HBT方法得到的关联函数强度可以很好地表征原子核内部核子之间联系的紧密程度,且原子核内部核子之间的关联函数强度与表征核子之间联系紧密程度的物理量存在着近似线形的关系.另外核物质状态方程(EOS)的HBT研究,也对确定合适的核物质状态方程具有重要的意义.

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. It discusses the relationship between the binding energy per nucleon of the projectiles and the strength of the neutron-proton HBT at small relative momentum. Moreover,the relationship between the single neutron separation energy and the strength of the halo neutron-proton HBT is revealed. Results show that neutron-proton HBT results are sensitive to binding energy or separation energy. Some researches about the Equation of State (EOS) have been completed, which show that the HBT results are also sensitive to the parameters of the EOS.
