[en] In the paper investigated are the properties of the π^-12C interaction at the momentum of pions psub(π) = 5 GeV/c leading to the production of neutral strange particles (Λ, K⁰) accompanied by protons. Ambiquity of the V⁰-particle identification is approximately 15%. Spectra of effective masses for Λ p and K⁰p systems, momentum proton spectra and distribution of events over the number of secondary protons for the events with Λ hyperons and K⁰ mesons are obtained. The principal results may be formulated as follows: 1) In the spectrum of effective masses of Λ p system only one maximum is observed at Msub(Λ p) = 2127 MeV/c². 2) Grouping of events is observed in the spectrum of effective masses of the K⁰p system at Msub(k⁰p) = (1810-1910) MeV/c² which may be the result of the Zsup(*) resonance production. 3) Ysup(* +)91385) and Ksup(* +)(890) resonance production may be distinctly observed. 4) Considerable fraction of the π^- nucleus interactions occurs in the same way as on free nucleons, and discrimination of the quasi-free interaction background is required for studying the possible Λ p and K⁰p resonances production in such collisions
