Abstract.The number of nucleon (NN) scaling of the directed flow v(1) and elliptic flow ( v2 as well as the nuclear modification factor ( Rcp are tested for light nuclei which are produced in 0.4A GeV Au-197 + Au-197 collisions at different impact parameters with two different in-medium nucleon-nucleon cross sections in the framework 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 phenomenon. The results show a nice NN scaling behavior for flow parameters v1 , v2 and Rcp . These results demonstrate that the nucleon coalescence mechanism is responsible for nucleon-number scaling of above physical observables in the squeeze-out region in heavy-ion collisions at intermediate energy.
