抄録

The spin symmetry of the anti-Lambda spectrum in nucleus ¹⁶O is studied in the relativistic mean field theory. The spin-orbit splittings of spin doublets are found to be around 0.03-0.07MeV and the dominant components of the Dirac spinor for the anti-Lambda spin doublets are found to be near identical. It is indicated that there is an even better spin symmetry in the anti-Lambda spectrum than that in the anti-nucleon spectrum.
