Abstract：
In this paper, we assume that proton, neutron and Λ hyperon are the basic particleswhich belong to the fundamental triplet of the group SU₃.Thus baryonium are to beclassified in the representations of SU₃.Besides, the "original" mass difference be-tween Λ hyperon and nucleon exhibits the violation of unitary symmetry which causesthe splittings of energy levels and leads to the formations of the "unitary symmetricalenergy band". The analysis in this paper of the energy levels of B-B systems shows theexistence of the energy band. Furthermore, we find that the theoretical values obtainedare consistent with the experimental ones quite well.
