“…24 Mg and 12 C+ 12 C have been extensively investigated over the last 40 years and a large body of experimental data has been accumulated from the systematic studies of these reactions (see [1][2][3] and references therein). A variety of theoretical accounts, based on dynamical models or purely phenomenological treatments, have been proposed to explain the experimental data [1,4,5].…”

We introduce a new coupling potential to explain the experimental data for the 12 C+ 24 Mg system at numerous energies in the laboratory system from 16.0 MeV to 24.0 MeV. This new coupled-channels based approach involves replacing the usual first derivative coupling potential by a new, secondderivative coupling potential. This paper first shows and discusses the limitation of the standard coupled-channels theory in the case where one of the nuclei in the reaction is strongly deformed. Then, this new approach is shown to improve consistently the agreement with the experimental data and has made major improvement on all the previous coupled-channels calculations for this system.

“…A variety of theoretical accounts, based on dynamical models or purely phenomenological treatments, have been proposed to explain the experimental data [1,4,5]. However, there appears no unique model that explains consistently the elastic and inelastic scattering data over wide energy ranges without applying any ad-hoc procedures.…”

“…The first approach that has been more popular with researchers so far attempts to describe the data by invoking the properties of the average Optical potential [10,[13][14][15][16][17][18][19]. On the other hand, in the second approach, the structure in the excitation function is associated with isolated or nearly isolated partial-wave resonances superimposed on the scattering properties of a standard Optical potential [1,2].…”

“…The physical origin of the observed structure is not yet fully understood [2,[4][5][6][7][8] and presents a challenge to different approaches that have been proposed to explain it. These approaches range from the occurrence of possibly overlapping shape resonances [9] and the scattering from surface-transparent Optical potentials [10] to more exotic effects like explicit parity-dependence of the ion-ion potential [11,12].…”

New results in the analysis of16O+28Sielastic scattering by modifying the optical potential

The elastic scattering of the 16 O+ 28 Si system has been analyzed with a modified potential within the framework of the optical model over a wide energy range in the laboratory system from 29.0 to 142.5 MeV. This system has been extensively studied over the years and a number of serious problems has remained unsolved: The explanation of the anomalous large angle scattering data; the out-of-phase problem between theoretical predictions and experimental data; the reproduction of the oscillatory structure near the Coulomb barrier; the consistent description of angular distributions together with the excitation functions data are just some of these problems. We propose the use of a modified potential method to explain these problems over this wide energy range. This new method consistently improves the agreement with the experimental data and achieves a major improvement on all the previous Optical model calculations for this system.
