Abstract

A common optical potential for ⁴He+¹²C at intermediate bombarding energies, which is essential in analyzing exotic nuclei with ⁴He clusters, was obtained based on the São Paulo potential (SPP). Among systematic optical potentials for ⁴He+¹²C, this potential has the merit of using a fixed imaginary part of Woods-Saxon form. By optical-model calculations, this potential reproduced the experimental elastic scattering angular distributions of ⁴He+¹²C well within the energy range of 26 A--60 A MeV. It was also applied successfully in calculations of the breakup reactions of ⁶Li+¹²C and ⁶He+¹²C with a three-body continuum discretized coupled-channels method.
