  We present a short review of anomalous properties in diffractive photo- and
electroproduction of radially excited V'(2S) vector mesons. Using the color
dipole gBFKL phenomenology we analyze anomalous Q^{2} and energy dependence of
the production cross section, V'(2S)/V(1S) production ratio, the diffraction
slope and anomalous t behaviour of the differential cross section d\sigma/dt.
The origin of these anomalies is based on the interplay of the nodal structure
of V'(2S) radial wave function with the energy and dipole size dependence of
the dipole cross section and the diffraction slope. We analyze how a different
pattern of anomalous behaviour of V'(2S) production leads to a different
position of the node in the wave function and discuss how that node position
can be extracted from the data at HERA.
