Production and structure of light Σ-hypernuclei
Description
The Σ-hypernuclear bound state 4ΣHe with Jπ = 0+ and T ∝ 1/2 (99%) is investigated on the basis of realistic ΣN interaction, with results which are in agreement with recent experimental observations. A complex nucleus-Σ potential derived has repulsion near the nuclear center in its real part, which suppresses the ΣN → ΛN conversion decay. To get infinite information on the width and the structure of the 4ΣHe, production spectra by 4He(K-, π-+) reactions in flight at pK = 600 MeV/c are examined theoretically within the DWIA framework. The structure of light nuclei with a Σ-hyperon is also discussed. (orig.)
