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