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.
