  The total and angular differential cross sections of the coherent process
$\bar p + {}^AZ \to {}^A_\Lambda(Z-1) + \bar{\Lambda}$ are evaluated at the
beam momenta $1.5\div20$ GeV/c within the meson exchange model with bound
proton and $\Lambda$-hyperon wave functions. It is shown that the shape of the
beam momentum dependence of the hypernucleus production cross sections with
various discrete $\Lambda$ states is strongly sensitive to the presence of the
scalar $\kappa$-meson exchange in the $\bar p p \to \bar\Lambda \Lambda$
amplitude. This can be used as a clean test of the exchange by scalar $\pi K$
correlation in coherent $\bar p A$ reactions.
