Color transparency effects for hole excitations in a(e, e'p) reactions

The color transparency effect is estimated for the hole excitation of the levels in high-Q² A(e, e'p) reactions which can be studied in the high-resolution experiments at CEBAF. We find that the optimal strategy in a wide Q² range where the effect is expected to be rather small would be to study transitions to the s-levels because (i) the effect is significantly enhanced for these transitions, (ii) the cross section in the absence of the color transparency effect can be reliably calculated for small nucleon momenta, (iii) the off-shell effects in the discussed kinematics are small.
