英文摘要	The heaviest observed antinucleus to date is (He-4) over bar which was detected at the STAR experiment at the Relativistic Heavy Ion Collider. From previous scattering experiments, we know that the Li-4 has a very short lifetime, about 1.197 x 10(-22) s, and can decay into proton and He-3. In experiments, the correlation function of (p) over bar-(He-3) over bar provides us a method to observe (Li-4) over bar. In this paper we use the blast-wave model and the Lednicky-Lyuboshitz analytical model to obtain a prediction of the correlation function of (p) over bar-(He-3) over bar with and without (Li-4) over bar decay in Au + Au collisions at root S-NN = 200 GeV. The magnitude of event number needed to detect (Li-4) over bar experimentally is estimated from the error of the correlation function. The correlation function with (Li-4) over bar decay is found to exhibit a peak at k* approximate to 0.073 GeV/c. The results offer a reference for the experimental search for (Li-4) over bar in relativistic heavy-ion collisions.
