Abstract

A crossover is observed in the differential cross sections for the inelastic processes

K^{0} p \to Q^{0} p

and

{\bar{K}}^{0} p \to {\bar{Q}}^{0} p

, from

{K_{L}}^{0} p

data in the momentum range from 4 to 12 GeV/c. This phenomenon is evidence that Regge, in addition to Pomeranchukon, exchanges contribute to

Q

-meson production.
