Abstract

Energy spectra of 0s-orbit Λ states in p-shell Λ hypernuclei (^A_ΛZ) and those in ¹⁹_Λ\textrmF are studied with the microscopic cluster model and antisymmetrized molecular dynamics using the G-matrix effective ΛN (ΛNG) interactions. Spin-dependent terms of the ESC08a version of the ΛNG interactions are tested and phenomenologically tuned to reproduce observed energy spectra in p-shell ^A_ΛZ. Spin-dependent contributions of the ΛN interactions to spin-doublet splitting and excitation energies are discussed. Energy spectra for unobserved excited states in p-shell ^A_ΛZ and ¹⁹_Λ\textrmF are predicted with the modified ΛNG interactions.
