The inclusive production of Ξ − and Ξ ∗0 (1530) is investigated in K − p interactions at 10 and 16 GeV/ c . The inclusive production cross sections are 172 ± 20 μ b and 135 ± 15 μ b for the Ξ − , and 43 ± 7 μ b and 32 ± 5 μ b for the Ξ ∗0 (1530) at 10 and 16 GeV /c , respectively. In the beam momentum range up to 16 GeV/ c , the energy dependence of the cross section for Ξ − production in K − p interactions is similar to Σ − production in π − p interactions. It is, instead, different from the energy behaviour of Σ − production cross sections observed in π − p interactions. The Ξ − and Ξ ∗0 (1530) are both produced more in the forward ( x > 0) than in the backward hemisphere, indicating the presence of hyperon-exchange processes.
