The spectrum of excited states in the hypernucleus Λ13C was studied at the Brookhaven Alternate Gradient Synchrotron using the (K-,π-) reaction on an enriched 13C target. γ rays coincident with the p1/2Λ state were observed using two large sodium iodide detectors. We interpret them as arising from the p1/2Λ→s1/2Λ transition in Λ13C. This represents the first direct observation of a γ ray associated with the transition of a hyperon between major nuclear shells.
