摘要：

A potential version of the UrQMD (UrQMD/M) transport model and a traditional coalescence model are combined to calculate the production of He-3 fragments in central Pb+Pb collisions at SPS energies 20-80 GeV/nucleon. It is found that the Lorentz transformation in the afterburner influences visibly the He-3 yield and should be considered in calculations. The rapidity distribution of He-3 multiplicities (including the concave shape) can be described well with UrQMD/M when it stops during t(cut)=(100 +/- 25) fm/c and the coalescence afterburner with one parameter set of (R-0,P-0)=(3.8 fm, 0.3 GeV/c) is taken into use afterwards.
