Abstract
We have studied the diffractive dissociation into dijets of 500 GeV/c pions scattering coherently from carbon and platinum targets. Extrapolating to a symptotically high energies (where t(min) --> 0), we find that when the per -nucleus cross section for this process is parametrized as sigma = sigma (0 )A(alpha), alpha has values near 1.6, the exact result depending on jet tra nsverse momentum. These values are in agreement with those predicted by the oretical calculations of color-transparency.
