Abstract

We evaluate the cross section of the process e+e-→γX(3872) in terms of the content of the D*0D̄0 "molecular" component in the wave function of the resonance X(3872). If this component is dominating, the cross section of the reaction e+e-→γX(3872) can reach up to about 10-3 of that for e+e-→D*D̄* at energy slightly above the D*D̄* threshold, and the considered process can be a realistic source of the X(3872) particles for the studies of this resonance.
