Within the framework of a semiclassical Boltzmann-Uehling-Uhlenbeck transport model,the high momentum tail (HMT) effects of nucleon momentum distribution in nucleus on the nucleoncollective flows are studied in semicentral $Au+Au$ collisions. The HMT due to the isospin-dependentshort range correlations(SRC) causes a smaller value of the collective flows. We find that the HMT effects on thenucleon collective flows are remarkable at beam energy of 300 MeV/nucleonand become weak as the incident beam energy increases.The results indicate that for the collective flow studies at intermediate energies, the HMT of nucleon momentumdistribution in nucleus should be taking into account in transport models.
Keywords:collective flows; transport model; HMT
