Sažetak
Measurements of exclusive incoherent electroproduction of ρ0 (770) meson from 2H, 12C, and 63Cu targets up to Q2 = 4 GeV2 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.
