Experimental and theoretical ratios of pairs of heavy-ion direct reactions of the form $A(a, b)B$ and $A(a, b)b$ where $b$ and $B$ are isobaric nuclei could be used to highlight the Coulomb effects on the neutron and proton form factors in a unique manner. These results quantitatively provide evidence for the need for including the Coulomb potentials in the interaction that causes transfer previously studied in terms of the theoretical post-prior equality of the transition amplitude.
