Abstract

The spectrum of excited states in the hypernucleus ¹³_ΛC was studied at the Brookhaven Alternate Gradient Synchrotron using the (K-, π- reaction on an enriched ¹³C target. γ rays coincident with the p_1/2Λ state were observed using two large sodium iodide detectors. We interpret them as arising from the p_1/2Λ → s_{1/2 Λ} transition ¹³_ΛC. in This represents the first direct observation of a γ ray associated with the transition of a hyperon between major nuclear shells.
