Color Dipole Systematics of Diffractive Photo- and Electroproduction of   Vector Mesons
  We present the first evaluation of color dipole cross section from experimental data on diffractive photo- and electroproduction of vector mesons. The dipole-size and energy dependence of the found dipole cross section is consistent with expectations from the BFKL dynamics.
