RESUMO
Coulomb excitation matrix elements are often expressed in terms of the scalar electric potential and the electromagnetic fields. We show that, through an appropriate gauge transformation, the excitation matrix elements can always be expressed in terms of the electromagnetic fields alone. This change in representation becomes important when the widths of the excited states are taken into account.
