Abstract

We have obtained the decay asymmetry parameters in non-mesonic weak decay of polarized Λ-hypernuclei by measuring the proton asymmetry. The polarized Λ-hypernuclei, _Λ⁵He, _Λ¹²C, and _Λ¹¹B, were produced in high statistics via the (π⁺, K⁺) reaction at 1.05 GeV/c in the forward angles. Preliminary analysis shows that the decay asymmetry parameters are very small for these s-shell and p-shell hypernuclei.
