✦ Synopsis

We explore some of the effects of optical-potential ambiguities on the fusion cross sections for heavy-ion collisions, especially at energies below the top of the Coulomb barrier when the barrier-penetration model is used. Ambiguities of the Igo type in the real potential are found to have little effect except when the potential is very shallow. The cross sections are seen to be very sensitive to the imaginary potential adopted if this allows for some absorption within the barrier: both the magnitude and shape of the excitation function may be changed.
