Study of A_2 production in the reaction π^-p→K^0K^-p at 50, 100, and 175 GeV/c

The reaction π^-p→K^0K^-p has been measured from 50 to 175 GeV/c. The production characteristics of the A_2 have been analyzed. We find spin and t dependence similar to lower energies, but the cross section falls rapidly with energy. In a Regge description of π^-p→A_2^-p our data imply a rather small Pomeron-exchange component
