Optical potential parameters from¹²C + Zr elastic scattering

Abstract

Abstract. The angular distributions of 12 C + 90,92,94,96 Zr elastic scattering were measured with the Q3D magnetic spectrometer at the HI-13 tandem accelerator, Beijing. The real part of optical potential were extracted by analysing these angular distributions. The analysis enable us to avoid the influence of Coulomb effect and to observe the dependence of optical potential on the nuclear properties. With the deduced potential parameters, the experimental elastic scattering angular distributions can be reproduced very well. Formulas to infer global heavy-ion potential parameters were obtained then by analyzing the extracted optical potential parameters. The formulas can be used widely in heavy-ion nuclear reactions.

“…The elastic-scattering angular distributions are also calculated using the obtained global OMP for some medium mass targets. For the 12 C + 90 Zr system, the calculations are compared with the corresponding experimental data [26,33,34], and they are in good agreement with the existing experimental data at all incident energies. These results are presented in Fig.…”

“…Good agreement on the elastic angular distribution is obtained between them. We compare the elastic angular distributions of 92 Mo with the data [34] in Fig. 9.…”
