The $ΛK$ system production in the hadron interactions
The A-dependence is observed in $x_F$-distributions for the $ΛK^0$ system produced with the small transverse momentum in the neutron-nucleus interactions. For the $Λ$ hyperons similar dependence isn't seen. The result is interpreted as an effect from intermediate excitative nucleon state, which decays into strange particles. Such interpretation is confirmed experimental data on $ΛK$ pair production in the pion-nucleon interactions.
