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