New data are reported on antiproton annihilations at rest with production of LAMBDA and K(S)0, using a streamer chamber with He-3, He-4 and Ne-20 as gas targets. The data include LAMBDA, K(S)0, LAMBDA-K(S)0 and K(S)0K(S)0 production rates and momentum distributions, pi- momentum spectra, mean numbers of charged particles generally and of negatively charged particles separately for different reaction channels. The yields are compared to simple combinatorial calculations based on the extreme assumptions of LAMBDA production via B = 1 or via B = 0 (KBAR rescattering) annihilations. LAMBDA and K(S)0 momentum spectra are compared to simple model calculations where B = 0 and B = 1 annihilations with and without final-state interactions are considered. A review of existing data on LAMBDA and K(S)0 production is presented, showing the dependence on the pBAR momentum and on the mass number of the target.
