English abstract Different from the case of the nonrelativistic limit, it is shown in this paper that in the ultrarelativistic limit, the L = j, j+1 wave components are large terms for both state with parity ηP = (−1)j and state with parity ηP = (−1)j+1. Moreover, it is found that the states with parity ηP = (−1)j are degenerate with the states with parity ηP = (−1)j+1 if the Lorentz structure of the interaction between the massless constituents is four-vector or time-component of four-vector. The scalar interaction violates this degeneracy
