dc.descriptionExperimental data as a stereo photographs from the 2m propane bubble chamber LHE, JINR have been analyzed for exotic multibaryon metastable and stable states searches. A number of peculiarities were found in the effective mass spectra of: 1)$Λπ^{\pm}$,$Λπ^+ π^-$, $Λp$, $Λp p$, $Λπp$,$ΛΛ$ and $ΛK^0_S$ subsystems. The observed well known $Σ^{*+}$(1385),$Λ^*(1600)$ and $K^{*\pm}$(892)resonances are good tests for this method. The width of $Σ^{*-}(1385)$ for p+A reaction is two time larger than that presented in PDG. The $Λπ^-$ spectrum observed enhancement in mass range of 1345 MeV/$c^2$ which interpreted as a stopped in nucleus $Ξ^-$. The cross section of stopped $Ξ^-$ production is $\approx$ 8 times larger than obtained by fritiof model with same experimental conditions.
