Structures and production cross sections of p-shell Lambda-hypernuclei calculated with multi-configuration shell model

Abstract

Abstract The high-resolution data of the 10B (e, e′K +) Λ 10 Be experiment done at the Jefferson National Laboratory reported a new bump, which cannot be explained by the DWIA calculation by employing the conventional shell-model wave functions. To describe the new bump, we have extended the model space by introducing a new configuration with 1ħω excitation for both nuclear and hyperon states. We show that the DWIA calculation by using the extended shell-model wave functions successfully explains the new bump for the first time, and that the p-state Λ in the lower molecular orbit plays an important role in the appearance of the new bump.
