Measurements of exclusive incoherent electroproduction of r0(770)
meson from 2H, 12C, and 63Cu targets up to Q2
= 4 GeV 2 are proposed using the CLAS detector at Jefferson Lab. The objective
of these measurements is to determine the Q2 dependence of the nuclear
transparency ratio for the two nuclear targets: 12C and 63Cu at
fixed coherence length of quark-antiquark fluctuations of the virtual photon. A sizeable
rise of the nuclear transparency is predicted and can be measured in this experiment. A
relatively large increase of the nuclear transparency can be considered as a signature of
the onset of color transparency.
