A missing-mass spectra has been studied for the different channel of reactions as: ’p’ (p,$K_s^0$), С (p,$K_s^0$), ‘p’(p,p$K_s^0$), С(p,p$K_s^0$) , ’p’(p, $\mathrm{\Lambda }$), C(p, $\mathrm{\Lambda }$),’p’(p, $K^{+})\mathrm{\Lambda }$, C(p,$K^{+})\mathrm{\Lambda }$ and so on. There are statistically small peaks (3-4 S.D.) which are observed by this method on mass range of $K^0$(498), $\mathrm{\Lambda }$(1520), $\varphi$(1020), $\mathrm{\Sigma }$ (2040), ${}^{3}H$, ${}^{4}He$ and so on. A good test of the method is observed the well known resonances for ${\mathrm{\Sigma }}^{+}$(1385) and $K^{\ast +}$(890). Statistically significant peaks were identified from reactions С(p,p$K_s^0$) and p (p, $\mathrm{\Lambda }){\pi }^{-}\gamma$ over a mass range of 11.36 (7.3 S.D.) and 3.2 GeV/$c^2$ (6. S.D.), which were interpreted as hyper-nucleus ${}^{12}$B and ($K^{-}$ppn) state predicted from kaon cluster model.
