Abstract

The NA52 experiment measured particle and antiparticle yields at 0° production angle over a wide range in rapidity in lead-lead (Pb-Pb) collisions at 158 A GeV/c with a minimum bias trigger. Besides O(10⁶) antiprotons (p̄) and O(10³) antideuterons ( d̄) a total of five antihelium-3 (³He) were found. The resulting invariant differential ³He production cross sections at p_t ≃ 0 GeV/c turn out to be E d³σ/dp³ = (2.5 ± 1.8) × 10^-7 bc³ GeV^-2 at a rapidity of y = 3.4 in the laboratory system and (5.9 ± 3.4) × 10^-8 bc ³ GeV^-2 at y = 4.0. The results are discussed in the framework of a simple coalescence model.
