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
Result description
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 - C-13(Lambda), O-17(Lambda), Ne-21(Lambda), Si-29(Lambda) and Ca-41(Lambda). 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 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.
