We study the decay phi-->gammaK(+)K(-), taking into account the scalar meso
n production phi-->gamma (f(o)+a(o)) --> gammaK(+)K(-) and final state radi
ation. We note that the relative sign between the final state radiation amp
litude and the scalar meson production amplitude is fixed in the K+K- loop
model which describes data on the phi -->gammaf(o)-->gamma pi pi and phi-->
ya(o)-->gamma pi eta decays. As a consequence this model predicts a definit
e interference between the final state radiation and the scalar resonance p
roduction amplitudes. We calculate the mass spectra of the (,phi-->gammaK()K(-) decay and the differential cross sections for e(+)e(-)-->phi gammaK()K(-) and e(+)e(-)-->phi -->gammaK(o)(K) over bar (o) reactions.
