[en] The information concerning ΛN and ΣN interactions obtainable from newly studied hypernuclear configurations is discussed, with the conclusion that the strong enhancement observed at the ΣN threshold is most probably due to the close relationship of the ³S₁ hyperon-nucleon interaction with the ³S₁ np interaction responsible for the deuteron. The K^- → π^- excitation of hypernuclear states at 0⁰ (strangeness analogue configurations) and at non-forward angles gives us the beginnings of a hypernuclear spectroscopy, whose study has already demonstrated that the ΛN potential has only a weak spin-orbit component. The existence of Σ-hypernuclear states is reported and discussed. The possibilities for narrow states, as observed for light nuclei, are very limited, and data concerning them will five us clear information concerning Σ-nucleon forces, in due course. (orig.)
