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^- p_x=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.
