测量了12c上（π+, K+）反应产生的非介子弱衰变质子（NM-p）和介子弱衰变介子（M-π）。通过质子非束缚态the11ΛB（5.2 +）产生的NM-p in12ΛC和准束缚区（Ex≈20 MeV） in12ΛC产生的NM-p和M-π相对于反应平面表现出A1=−0.20 ~−0.35的有限不对称性。这些结果表明了相关Λ-hypernuclei和不对称NM弱衰减的有限极化。
Non-mesonic weak-decay protons (NM-p) and mesonic weak-decay pions (M-π) from Λ produced by the (π+, K+) reaction on12C have been measured. NM-p from the11ΛB ( 5 2+) produced through the proton-unbound states in12ΛC and NM-p and M-π associated with the quasi-bound region (Ex≈ 20 MeV) in12ΛC show finite asymmetries of A1= − 0.20 to − 0.35 with respect to the reaction plane. These results indicate finite polarizations of the relevant Λ-hypernuclei and asymmetric NM weak decays.
