Abstract :
The interpretation of hypernuclear γ-ray data for p-shell hypernuclei in terms of shell-model calculations that include the coupling of Λ- and Σ-hypernuclear states is briefly reviewed. Next, image and image are considered, both to exhibit features of Λ–Σ coupling and as possible source of observed, but unassigned, hypernuclear γ-rays. Then, the feasibility of measuring the ground-state doublet spacing of image, which, like image, could be studied via the image reaction, is investigated. Structural information relevant to the population of states in these hypernuclei in recent image studies is also given. Finally, the extension of the shell-model calculations to sd-shell hypernuclei is briefly considered.
