英文摘要	We have precisely derived a "rigorous instantaneous formulation" for transitions between two bound states when the bound states are well-described by instantaneous Bethe-Salpeter (BS) equation (i.e. the kernel of the equation is instantaneous "occasionally"). The obtained rigorous instantaneous formulation, in fact, is expressed as an operator sandwiched by two "reduced BS wave functions" properly, while the reduced BS wave functions appearing in the formulation are the rigorous solutions of the instantaneous BS equation, and they may relate to Schrodinger wave functions straightforwardly. We also show that the rigorous instantaneous formulation is gauge-invariant with respect to the U-em(1) transformation precisely, if the concerned transitions are radiative. Some applications of the formulation are outlined.
