Abstract
In this experiment, 32S interaction with emulsion nuclei is examined at 3.7A and 200A GeV. Backward relativistic hadron production seems to be an exact decay system, depending on the target size. For emulsion nuclei, the decay constant of this system nearly equals 1.3. Independent of the projectile size and energy, the backward relativistic hadrons are produced with probability value of ~20%-30%. For projectile nuclei with mass number greater than or equal to 6 and at any incident energy, the average multiplicity of these backward hadrons tends to a saturation value of ~0.4. Regarding the multiplicity range of forward relativistic hadrons, reaching 60 hadrons per event at 3.7A GeV and extending to ~400 hadrons per event at 200A GeV, energy plays a fundamental role in forward relativistic hadron production. The results strongly support the assumption that relativistic hadrons are created as a result of energy from participant nucleons.
