We precisely measured π0 branching ratios of Λ5He and Λ12C hypernuclei produced via the (π+, K+) reaction. Using these π0 branching ratios with the π- branching ratios and lifetimes, we obtained the π0 decay widths and the non-mesonic weak decay widths with an accuracy of ∼5% (stat) for both hypernuclei.
