摘要Hypernuclear magnetic moment and λ--N interaction in 17λO has been studied within relativistic mean field theory. Without core polarization, the relativistic results are found to fit the Schmidt value well and not be sensitive to λ--N interaction. The relativistic magnetic moment is enhanced with nearly equal contributions of the relativistic and free masses. When λ hyperon occupies the l=0 or l=1 orbit, the effect of λ--N interaction on the magnetic moment of valence proton is different.
