The role of $f_{0}(980)$ and
$a_{0}(980)$ scalar meson intermediate states in the mechanism of
radiative $phi (1020)$ meson decay into two charged $K (494)$
mesons and a photon $phirightarrow K^{+} + K^{-} + gamma$ is
investigated. For the contribution of scalar meson intermediate
state two models are considered. In the kaon-loop model, the scalar
meson intermediate state couples the final state to the initial
$phi$ meson through a charged kaon-loop. The second model, called
no-structure model, consist of point-like coupling of intermediate
scalar meson state to the initial state. It is found that in the
kaon-loop model, scalar meson intermediate state results in a
considerable modification of the pure Bremsstrahlung photon
spectrum.
