Abstract

Results are reported on a lifetime measurement of Λ4H formed in 4He (stopped K-,π°) reaction. Decay of Λ4H was clearly identified by observing the monochromatic π- peak from the two-body decay (Λ4H → 4He + π- px=132.9 MeV/c). The lifetime of Λ4H was determined to be τ(Λ4H) = 194-26+24 ps from a distribution of time difference between the K- injection and π- emission.
