“…The fit shows clearly the incompatibility between our model and the results of several groups. The agreement is very good with the experimental data of Eisen et al [42] and of Lee et al [43]. The data of Dauk et al [44] are not consistent with our model and with the data at higher energies.…”

We present a barrier-penetration model for heavy-ion fusion valid from the lowest energies available up to the largest energies for which the critical-radius picture is realistic. The parameters of the model are a critical radius and the parameters of a nucleus-nucleus interaction, whose form factor can be chosen freely. Fusion cross sections for a large number of systems, for which low-energy data exist, are fitted with a Woods-Saxon potential. Realistic parameters are obtained for the Coulomb barrier. Different applications and some limitations of the model are discussed.

“…The quest for understanding of the reaction mechanism with the 16 O+ 27 Al reaction already started as early as 1959 [2]. Since then, along with continuous development of experimental techniques, numerous measurements were carried out for this system to identify, e.g., interplay between incomplete fusion and projectile breakup processes [3][4][5][6][7][8][9][10], and the mechanism of complete fusion [11][12][13][14][15][16][17][18]. Measurements for deep-inelastic and transfer processes were also performed [19][20][21][22][23][24][25][26][27][28][29][30][31][32].…”

Deep-inelastic multinucleon transfer processes in the O16+Al27 reaction

et al. 2018

The reaction mechanism of deep-inelastic multinucleon transfer processes in the 16 O+ 27 Al reaction at an incident 16 O energy (E lab = 134 MeV) substantially above the Coulomb barrier has been studied both experimentally and theoretically. Elastic-scattering angular distribution, total kinetic energy loss spectra and angular distributions for various transfer channels have been measured. The Q-value-and angle-integrated isotope production cross sections have been deduced. To obtain deeper insight into the underlying reaction mechanism, we have carried out a detailed analysis based on the time-dependent Hartree-Fock (TDHF) theory. A recently developed method, TDHF+GEMINI, has been applied to evaluate production cross sections for secondary products. From a comparison between the experimental and theoretical cross sections, we find that the theory qualitatively reproduces the experimental data. Significant effects of secondary light-particle emissions are demonstrated. Possible interplay between fusion-fission, deep-inelastic, multinucleon transfer and particle evaporation processes are discussed. arXiv:1707.04164v2 [nucl-ex]

We perform a comprehensive analysis of complete fusion cross section data with the aim to derive, in a completely data-driven way, a model suitable to predict the integrated cross section of the fusion between light to medium mass nuclei at above barrier energies. To this end, we adopted a novel artificial intelligence approach, based on a hybridization of genetic programming and artificial neural networks, capable to derive an analytical model for the description of experimental data. The approach enables, for the first time, to perform a global search for computationally simple models over several variables and a considerable body of nuclear data. The derived phenomenological formula can serve to reproduce the trend of fusion cross section for a large variety of light to intermediate mass collision systems in an energy domain ranging approximately from the Coulomb barrier to the onset of multi-fragmentation phenomena.
