We present the first measurements of transverse momentum spectra of pi +/-, K +/-, p(p over bar ) at midrapidity (|y| < 0.1) in U+U collisions at root sNN = 193 GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The centrality dependence of particle yields, average transverse momenta, particle ratios and kinetic freeze-out parameters are discussed. The results are compared with the published results from Au+Au collisions at root sNN = 200 GeV in STAR. The results are also compared to those from A Multi-Phase Transport (AMPT) model.
