Within the color dipole gBFKL dynamics applied to the diffraction slope wepredict an anomalous t dependence of the differential cross section as afunction of energy and Q^2 for production of radially excited V'(2S) lightvector mesons in contradiction with a well known standard monotonous t-behaviour for V(1S) mesons. The origin of this phenomenon is based on theinterplay of the nodal structure of V'(2S) radial wave function with the energyand dipole size dependence of the color dipole cross section and of thediffraction slope. We present how a different position of the node in V'(2S)wave function leads to a different form of anomalous t- behaviour of thedifferential cross section and discuss a possibility how to determine thisposition from the low energy and HERA data.Comment: 15 pages and 2 figure
