Abstract

The yields of identified particles have been measured at RHIC for Au+Au collisions at S N N = 200 GeV using the PHOBOS spectrometer. The ratios of antiparticle to particle yields near mid-rapidity are presented. The first measurements of the invariant yields of charged pions, kaons and protons at very low transverse momenta are also shown.
