英文摘要: We take the (mu(+/-)e(-/+)) system as an example, but restrict ourselves to highlight the states with quantum number J(P) = 0(-), to explore the different contents of the instantaneous Bethe-Salpeter (BS) equation and its analog, the relativistic version of Breit equation, by solving them exactly. The results show that the two equations are not equivalent, although they axe analogous. Furthermore, since the Breit equation contains extra un-physical solutions, so we point out that it should be abandoned if one wishes to have an accurate description of the bound states for the instantaneous interacting binding systems.
