Screening effects on ^(12)C+^(12)C fusion reaction

Chinese Physics C 2018年第5期42卷 91-98页

作者： F.Koyuncu A.Soylu Department of Physics Nigde ?mer Halisdemir University

One of the important reactions for nucleosynthesis in the carbon burning phase in high-mass stars is the12C+12C fusion reaction. In this study, we investigate the influences of the nuclear potentials and screening effect on astrophysically interesting12C+12C fusion reaction observables at sub-barrier energies by using the microscopic α-αdouble folding cluster(DFC) potential and the proximity potential. In order to model the screening effects on the experimental data, a more general exponential cosine screened Coulomb(MGECSC) potential including Debye and quantum plasma cases has been considered in the calculations for the12C+12C fusion reaction. In the calculations of the reaction observables, the semi-classical Wentzel-Kramers-Brillouin(WKB) approach and coupled channel(CC)formalism have been used. Moreover, in order to investigate how the potentials between12C nuclei produce molecular cluster states of24Mg, the normalized resonant energy states of24Mg cluster bands have been calculated for the DFC potential. By analyzing the results produced from the fusion of12C+12C, it is found that taking into account the screening effects in terms of MGECSC is important for explaining the12C+12C fusion data, and the microscopic DFC potential is better than the proximity potential in explaining the experimental data, also considering that clustering is dominant for the structure of the24Mg nucleus.

By adopting different neutron and proton density distributions,cluster decay half-lives were investigated using double-folding potentials with constant and nuclear asymmetry dependent sets of nuclear density *** adopted asymmetry dependent sets of parameters were fitted based on microscopic calculations,and they were calculated based on the neutron skin/halo-type nuclei assumption and by employing experimental rms charge radii.A bulk agreement between theory and experiment was obtained for all sets of parameters using a calculated cluster preformation *** differences were observed between the skin and halo-type ***,the notable role of the asymmetry parameter was observed in the relatively large differences between the skin and skintype with zero thickness.
