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.
