| Abstract: | Two-body collisions are included in TDHF by the time-relaxation method. Calculations are made in a one-dimensional slab-geometry at . The relaxation time is assumed to be temperature dependent. Results arc shown for two functions of the temperature as well as for ordinary TDHF (infinite relaxation time). Temperature and the two components of the pressuretensor (perpendicular and parallel to the beam direction) are shown. The approach towards the hydrostatic limit (isototropic pressure) as the relaxation time decreases is shown. Relaxation time is expected to decrease with temperature, i.e. beam energy. The energy at which the pressure becomes isotropic is important for understanding the dynamics of heavy ion collisions. |
