摘要: The number of nucleon (NN) scaling of the directed ow v1 and elliptic ow (v2) as well as thenuclear modi#12;cation factor (Rcp) are tested for light nuclei which are produced in 0.4A GeVAu +Au collisions at di#11;erent impact parameters with two di#11;erent in-medium nucleon-nucleon cross sections in aframework of an isospin-dependent quantum molecular dynamics (IQMD) model. In that energy domain,the emission of light nuclei can be well described by the squeeze-out phenonomenon. The results show anice NN scaling behavior for ow parameters v1, v2 and Rcp. These results demonstrate that the nucleoncoalescence mechanism is responsible for nucleon-number scaling of above physical observables in squeezeout region in heavy-ion collisions at intermediate energy.
