. The FINUDA experiment studies the Λ -hypernuclei formation and decay using the reaction ( K - stop ,π - induced by the low-momentum K - from the deacy of the φ -meson produced at the ( e + , e - collider DAφ NE at the Laboratory Nazionali di Frascati of INFN. In this paper we present new data on the proton spectra following the weak decay of 12 Λ C .
