Abstract

The production of deuterons and anti-deuterons in the transverse momentum range 1.1 <pT< 5.0 GeV/c at mid-rapidity in Au+Au collisions at GeV has been studied by PHENIX for six different centralities. The coalescence of neutrons and protons into deuterons as a function of pT and Npart has been studied. The large RCP of deuterons at intermediate pT is consistent with neutron production having similar centrality dependence to that of protons.
