    Figures & Tables(5)
    Particle scatter plot in the reaction plane for Au+Au collisions with impact parameter b=6 fm at beam energies of Elab=0.4A GeV and 0.8A GeV
    Time evolution of px2, py2, pz2, px2-py2, px2+py2, and pt of traced nucleons calculated without Fermi momentum, with Fermi momentum, and with half-Fermi momentum at a beam energy of Elab= 0.4A GeV
    (a) Time evolution of v2 of traced nucleons calculated without Fermi momentum, with Fermi momentum, and with half-Fermi momentum at a beam energy of Elab= 0.4A GeV, (b) time evolution of v2 of traced nucleons without Fermi momentum and with Fermi momentum at a beam energy of Elab= 0.8A GeV
    Time evolution of Δv2mf(t) and Δv2coll(t) of traced nucleons calculated (a) without Fermi momentum and (b) with Fermi momentum at a beam energy of Elab= 0.4A GeV. (a1, b1) The same as the left panels but at a beam energy of Elab= 0.8A GeV. The lines are smooth curves fitted through the calculated points.
    Time evolution of the number of collisions per event experienced by traced nucleons with and without Fermi momentum at a beam energy of Elab=0.4A GeV
