Sensitivity of {\Lambda} single-particle energies to the {\Lambda}N spin-orbit coupling and to nuclear core structure in p-shell and sd-shell hypernuclei
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 {\Lambda} hypernuclei - 13{\Lambda}C, 17{\Lambda}O, 21{\Lambda}Ne, 29{\Lambda}Si and 41{\Lambda}Ca. The hypernuclear spectra are compared with the results of a relativistic mean field (RMF) model and available experimental data. The sensitivity of {\Lambda} single-particle energies to the nuclear core structure is explored. Special attention is paid to the effect of spin-orbit {\Lambda}N interaction on the energy splitting of the {\Lambda} single particle levels 0p3/2 and 0p1/2. 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.
