We report results on the ratio of mid-rapidity anti-proton to proton yields in Au+Au collisions at $\rts=130$ GeV per nucleon pair as measured by the STAR experiment at RHIC. Within the rapidity and transverse momentum range of $|y|<0.5$ and $0.4 <pt< 1.0$ GeV/c, the ratio is essentially independent of either transverse momentum or rapidity, with an average of 0.65±0.01(stat.)±0.07(syst.) for minimum bias collisions. Within errors, no strong centrality dependence is observed. The results indicate that at this RHIC energy, although the $p-\pb$ pair production becomes important at mid-rapidity, a significant excess of baryons over anti-baryons is still present.
