Abstract

We evaluate the cross section of the process e+eγX(3872)e^+e^- \to \gamma X(3872) in terms of the content of the D0Dˉ0D^{*0} {\bar D}^0 `molecular' component in the wave function of the resonance X(3872). If this component is dominating, the cross section of the reaction e+eγX(3872)e^+e^- \to \gamma X(3872) can reach up to about 10310^{-3} of that for e+eDDˉe^+e^- \to D^* {\bar D}^* at energy slightly above the DDˉD^* {\bar D}^* threshold, and the considered process can be a realistic source of the X(3872) particles for the studies of this resonance.
