A non-perturbation approach to decay problems is presented. The results may be applicable to strong interaction decays provided that the width is sufficiently small. For weak interaction decays, including that of the neutral kaon, all the results are identical with those of perturbation theory. As a limit of the case with two unstable states with different masses, lifetimes and decay modes, we consider the unstable state associated with double pole. Although before taking the limit we need two unstable states, after taking the limit the double pole unstable state does not have a partner. Some discussion is given of the difference between the resonances (decay through strong interaction) and the unstable particles (decay through weak interaction).
