The problem of nucleon propagation through the nuclear medium in quasielastic A(e,e'p) reactions is discussed in the kinematic range 1 less than or equal to Q(2) less than or equal to 7 (GeV/c)(2). Experimental data are available from SLAC, BATES, and, recently, also from TJNAF. The coefficient of nuclear transparency is calculated for each Q(2) in the framework of the intranuclear cascade model (INC) and of the eikonal approximation (EA). The former has the capability of directly implementing the detector acceptances giving a very detailed analysis of the different observables. The latter, essentially based on an exclusive mechanism, contains explicit information about the dependence on the target shell structure. The predictions of both models are in good agreement with each other. The INC model reproduces the experimental data quite well in the measured range. The EA gives an explanation of the Q(2) behavior of the transparency coefficient as a kinematic effect related to the superposition of contributions from each target shell. [S0556-2813(98)03405-0].
