Abstract
Results are reported on the precise measurement of the lifetime and the weak-decay branching ratios with charged particle(π- and proton) emission from 12ΛC formed via 12C(π+,K+) reaction. The π- mesonic decay width is consistent with the calculations including the pion wave function distortion effect. We observed large contribution of the neutron-stimulated decay widths, Γ(Λ + n → n + n), in the non-mesonic weak decay, which cannot be explained by the current theoretical calculations.
