摘要：

We investigate antinuclei production in Ph + Pb interactions at 158 GeV/c per nucleon at zero degree production angle. We quote invariant differential production cross sections for antiprotons and antideuterons. The corresponding antideuteron to antiproton ratio at midrapidity is 4.2 . 10(-4). One antihelium-3 nucleus was observed. The results are discussed in the framework of a simple coalescence model.
