Abstract
The annihilation of ppBAR at rest into K(L)0K(S)0pi0 and K(L)0K(S)0eta was investigated with the Crystal Barrel detector at LEAR. These fina l states with negative C-parity are dominated by phi and K0 resonance s. The ratios of the branching ratios are B(ppBAR-->phipi0)/B((ppBAR-- >phieta) = 8.3+/-2.1 and B(ppBAR-->K0K0BAR + ->K(L)0K(S)0pi0)/B(ppBAR -->phipi0-->K(L)0K(S)0PI0) = 2.04+/-0.21.
