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.10 pages, 5 figures; accepted by Journal of Physics G: Nuclear and Particle PhysicsNuclear TheoryNuclear Experimenttext
