We measured the cross section of the reaction ..pi../sup -/p..--> lambda..K/sup 0/ and the ratio of the cross sections ..gamma.. =dsigma/duvertical-bar/sub u/max(..pi../sup -/p..--> lambda..K/sup 0/)/ d/sup 2/sigma/dudM/sup 2//sub x/vertical-bar/sub u u/max (..pi../sup -/p..--> lambda..X) (M/sup 2//sub x/=0.45--0.70 GeV/sup 2/) at momenta p/sub 0/=2.13, 2.69, and 3.25 GeV/c. This ratio depends little on p/sub 0/ in the interval from 2.13 to 8 GeV/c (calculated from the data of Foley et al., Phys. Rev. 10D, 2763, 1974). This points to the existence of a relative scale invariance in the reaction ..pi../sup -/p ..--> lambda..X.
