Abstract

The missing mass spectra for the ¹²C(p, K⁰_s) and ¹²C(p,Λ) reactions have been studied by using of the propane bubble chamber(PBC) data from 700000 stereo photographs or 10⁶ inelastic interactions. The momentum spectrum of π^- in range of 100-200 MeV/c have observed the significant enhancement from the p+C→ π^-ΛX(p+C→π^-K⁰_sX) reaction. The missing mass spectra have been observed signals for the p(p,π^-K⁰_s), ³H(p,pK⁰_s), p(p,Λ)π^-γ and p(p,π^-)Λ reactions. This experimental study will need to continue by using of a different identification methods for a reaction channels.
