Abstract:	Measurements have been performed on production of particles with mass 1.5 GeV/c² and charge $? 23$ for θ_lab = 62.5° and $s = 53 GeV$ . At p_T = 0.7 GeV/c the relative rate of production of antideuterons to π^? is (5 ± 1) × 10^?5. The deuteron to antideuteron ratio is 3.7 ± 1.2. No new stable particle has been amongst 0.7 × 10⁸ charged particles entering our detector.
