Abstract It is argued that the longitudinal part of space-like photon in its Breit frame is unable to transform into vector meson. Starting from this argument and adding a small amount of diquark component into the nucleon structure functions in nuclei, the A dependence of the RA = σAL /σAT value observed in electron nucleus DIS by the SLAC Group is explained.
