  We present predictions for the formation of (anti)nuclear bound states in
nucleus-nucleus reactions at RHIC energies. he phase space coalescence method
is used in combination with RQMD-v2.4 transport calculations to demonstrate the
relevance of particle production as well as the longitudinal and transverse
flow components. The formation of deuterons follows an approximate scaling law
proportional to the relative freeze-out densities of nucleons and produced
secondaries. For antideuterons, an additional suppression appears that is
proportional to the number of nucleons, pointing toward multiple rescattering
and absorption prior to freeze-out.
