• In view of the recent experimental evidence indicating m_<K^0>>m_<K^+>, in contrast with the well established result m_<π^+>>m_<π^0>, the problem of the electromagnetic meson self-masses is reinvestigated. A semi-phenomenological approach is used by the introduction of a nonlocal offective interaction hamiltonian, gauge invariant up to the order e^2, where new terms corresponding to one-photon and two-photon vertices are considered, to take into account the effects of the strong interactions. It is shown that the contrasting experimental result can be explained as the result of the different nature of the neutral kaons as compared with the neutral pion. Some different ways to realize the experimental results are explicitly discussed.
