## Abstract

We introduce a mean field model based on realistic 2-body baryon interactions and calculate spectra of a set of p-shell and sd-shell Λ hypernuclei – ^{13} _{Λ}C, ^{17} _{Λ}O, ^{21} _{Λ}Ne, ^{29} _{Λ}Si and ^{41} _{Λ}Ca. The hypernuclear spectra are compared with the results of a relativistic mean field (RMF) model and available experimental data. The sensitivity of Λ single-particle energies to the nuclear core structure is explored. Special attention is paid to the effect of spin–orbit ΛN interaction on the energy splitting of the Λ single particle levels 0p_{3/2} and 0p_{1/2}. In particular, we analyze the contribution of the symmetric (SLS) and the anti-symmetric (ALS) spin–orbit terms to the energy splitting. We give qualitative predictions for the calculated hypernuclei.
