Abstract High momentum transfer electrodisintegration of polarized and unpolarized deuterium targets,d(e, e′p)n is studied. We show that the importance of final state interactions FSI, occuring when a knocked out nucleon interacts with the other nucleon, depends strongly on the momentum $$\vec p_n $$ of the spectator nucleon. In particular, these FSI occur when the essential contributions to the scattering amplitude arise from internucleon distances ∼1.5 fm. But the absorption of the high momentumγ * may produce a point like configuration, which evolves with time. In this case, the final state interactions probe the point like configuration at the early stage of its evolution. If the point like configuration is still small after propagating about 1.5 fm, the FSI are suppressed. The result is that significant color transparency effects, which can either enhance or suppress computed cross sections, are predicted to occur forQ 2≳4GeV2. We suggest searching for color transparency phenomenon by examining ratios of experimentally measured quantities. Possible theoretical uncertainties of the calculations, including those due to the deuteron wave function and relativistic effects, are found to be small.
