Systematic studies of binding energy dependence of neutron-proton momentum correlation function

Hanbury Brown–Twiss (HBT) results of the neutron–proton correlation function have been systematically investigated for a series of nuclear reactions with light projectiles with the help of the isospin-dependent quantum molecular dynamics model. The relationship between the binding energy per nucleon of the projectiles and the strength of the neutron–proton HBT at small relative momentum has been obtained. Results show that neutron–proton HBT results are sensitive to the binding energy per nucleon.
