The energy dependence of the algebraic potential for heavy-ion elastic scattering near to the Coulomb barrier is investigated. The inclusion of an additional term in the complex algebraic potential to take into account the reflection due to the imaginary well is proposed. With this new term 12 elastic scattering angular distributions of the O16+63Cu system ranging from E=39 to 64 MeV in the laboratory system were analyzed. The real and imaginary strengths of the algebraic potential exhibit a dependence with energy similar to the dispersive behavior associated with the threshold anomaly. © 1994 The American Physical Society.
