Spin Symmetry for Anti-Lambda Spectrum in atomic nucleus

Abstract

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