Abstract
We present the observation of the \Heebar nucleus, the heaviest antinucleus observed to date. In total, 18 \Heebar counts were detected at the STAR experiment at RHIC in 10 recorded Au+Au collisions at beam energies of = 200 GeV and 62 GeV. The background has been estimated, and the misidentification probability is found to be lower than 10.
