Abstract Antilambda production is studied inK − p interactions at 32 GeV/c. Both total and differential cross sections are presented. The inclusive $$\bar \Lambda $$ production cross section amounts to 109±7 μb. A remarkable energy dependence is observed, σ( $$\bar \Lambda $$ ) increasing by a factor of four between 14.3 and 32 GeV/c. Thep ⊥ 2 distribution exhibits an exponential fall-off with a slope of 3.3±0.2 (GeV/c)−2. Most of the $$\bar \Lambda $$ 's are emitted in the forward hemisphere. The invariantx distribution increases between 14.3 and 32 GeV/c. Data are presented for $$\bar \Lambda $$ production inK - p→Λ $$\bar \Lambda $$ +X K - p→ $$\bar \Lambda $$ K n +X, andK - p→ $$\bar \Lambda $$ p+X.
