Abstract

Recent developments in hypernuclear spectroscopy are reviewed. For Λ hypernuclei we summarize the systematics of Λ single-particle levels, particularly for the 1s_Λ ground state, as revealed recently by the (π⁺, K⁺) spectra measured at BNL on several nuclei from ⁹Be to ⁸⁹Y. For Σ hypernuclei we discuss the difficulties encountered in relating the structures observed in K^- initiated reactions at CERN, BNL and KEK to Σ-nuclear interaction parameters. Some results of a recent shell-model study are reported in order to exhibit the interplay between the spin (including spin orbit) and isospin dependence of the ΣN effective interaction for the A = 12, 16 Σ-hypernuclear systems, provided these structures represent genuine excitations.
