Abstract
The realizations of spin symmetry in the hyperon spectra of hypernuclei ranging from light to heavy masses are investigated in the framework of the deformed Skyrme-Hartree-Fock approach. The effect of deformation on spin symmetry and its interplay with the required spin-orbit force is studied in detail. It is found that the spin symmetry prevails due to a small spin-orbit force. Moreover, for spin doublets with the same principal quantum number , the reduced spin-orbit splitting shows a good linear relation with respect to the quantum number , even for a large spin-orbit strength.
