Light s hypernuclei in four-body cluster models

Detailed structure calculations in ¹²Be, ⁷ H and ¹⁰Li are performed within the framework of the microscopic of four-body cluster models. We adopted effective EAT interactions derived from the Nijmegen interaction models, which give rise to substantially attractive E-nucleus potentials in accordance with the experimental indications. and ¹⁰Li are predicted to have bound states. we propose to observe the bound states in future (K, K+) experiments using ⁷Li and ¹⁰B targets in addition to the standard ¹²C target. The experimental confirmation of these states will provide information on the spin- And isospin- Averaged EN interaction.
