Abstract:
Using a microscopic transport model together
with a
coalescence after-burner, we study the
formation of
deuterons in Au + Au central collisions at
$\sqrt{s}=200
AGeV$. It is found that the deuteron
transverse momentum
distributions are strongly affected by the
nucleon
space-momentum correlations, at the moment of
freeze-out,
which are mostly determined by the number of
rescatterings.
This feature is useful for studying collision
dynamics at
ultrarelativistic energies.
