    The first preliminary data from the BRAHMS experiment at RHIC from Au-Au collisions at SNN=130 GeV has been reported. ¿From 3 independent detectors we have obtained the pseudo-rapidity density for the most 0-6% central Au-Au collisions dN/dη of ≈ 530 with an systematic error of 10%. Particle ratios pions and kaons are close to unity at mid-rapidity. The ratio of antiprotons to protons is significantly below unity at mid-rapidity, and decrease at forward rapidity. The rapidity dependence serves as a strong indicator of the balance between stopping of projectile baryons and anti-baryon baryon production. The BRAHMS collaboration wishes to thank the C-AD department of BNL for successful commissioning of RHIC and the contributions to the construction of the experiment. This work was supported by the Division of Nuclear Physics of the Office of Science of the U.S. Department of Energy under contract with BNL (No. DE-AC02-98CH10886), Texas A&M (DE-FG03-93ER40773), U.Kansas (DE-FG03-96ER40981), NYU (DE-FG02-99ER41121), the Danish Natural Science Research Council, the Korea Research Foundation Grant, the Norwegian Natural Science Research Council, the Jagiellonian University Grant, and the Romanian Ministry of Education and Research.
