## Abstract

Abstract: The EPR-type strangeness correlation in the \PKz \PaKz ~system produced in the reaction $\Pap \Pp \rightarrow \PKz \PaKz$ at rest has been tested using the CPLEAR detector. The strangeness was tagged via strong interaction with absorbers away from the creation point. The results are consistent with the QM non-separability of the wave function and exclude a spontaneous wave-function factorisation at creation (CL $99.99\%$).
