“…The nucleus-nucleus potential is a key component in any analysis of nuclear reactions, and can be used to estimate the cross sections of different nuclear reactions [1][2][3][4]. It has been of great interest to study the optical potential in heavy ion physics for many years [1][2][3][4][5][6][7][8][9][10].…”

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.

“…For this purpose, we have selected the fusion reactions which the C, O, Mg, Si, S, Ca, Ar, Ti and Ni isotopes are as their participant nuclei. In this study, the nuclear part of interacting potential has been calculated using four versions of proximity model, namely AW 95 [6], Bass 80 [7,8], Denisov DP [9] and Prox. 2010 [10] potentials.…”

The behaviors of barrier characteristics and fusion cross sections are analyzed by changing neutron over wide range of colliding systems. For this purpose, we have extended our previous study (Eur. Phys. J. A 48, 21 (2012), it is devoted to the colliding systems with neutron-rich nuclei) to 125 isotopic systems with condition of 0.5 ≤ N/Z ≤ 1.6 for their compound nuclei. The AW 95, Bass 80, Denisov DP and Prox. 2010 potentials are used to calculate the nuclear part of interacting potential. The obtained results show that the trend of barrier heights V B and positions R B as well as nuclear V N and Coulomb V C potentials (at R = R B ) as a function of (N/Z − 1) quantity are non-linear (second-order) whereas the fusion cross sections follow a linear-dependence. 25.60.Pj, 25.70.Jj

The Coulomb barrier parameters have been calculated for a spherical-deformed interacting pair of nuclei using fourteen different versions of the proximity approaches and a simple analytical formula for the Coulomb part of the heavy ion potential. The results of these proximity versions have been compared with more accurate results obtained from the double folding model (DFM). We have considered the interacting pair 48 Ca + 238 Pu as an example and assumed the presence of the quadrupole, octupole and hexadecapole deformation parameters for 238 Pu. The orientation angle dependence of the Coulomb barrier parameters has been computed for different sets of the deformation parameters. We found that the proximity types named; Prox77, BW Prox91, AW Prox95, Bass Prox77 and Bass Prox80 are the best ones of the available fourteen versions of the proximity approaches for calculating the nuclear part of the interaction potential for a spherical-deformed pair of nuclei.
