Abstract

The variation of the coherence length l_c=2ν/(Q²+m_V²) in virtual photoproduction of vector mesons off nuclei as a function of the photon energy ν or virtuality Q² results in dramatic changes in the values of the nuclear transparency. Color transparency effects can be easily mixed up with the effects of the coherence length in incoherent photoproduction on nuclei.
