Potential Parameters

Alpha elastic scattering of [Formula: see text]-nuclei was studied for calculating optical potentials. Choice of the [Formula: see text]-optical potentials is important to measure the reaction rates of [Formula: see text]-process. [Formula: see text] and [Formula: see text] elastic scattering cross-section data were used to determine the potential parameter sets at [Formula: see text][Formula: see text]MeV for [Formula: see text] and [Formula: see text], 18.8[Formula: see text]MeV for [Formula: see text] system. A Wood–Saxon potential form factor is used for both real and imaginary parts. The potential parameters extracted in the present study exhibit a satisfactory result with respect to existing global potential parameters.

Section Data

We discuss novel dispersion relations in differential form, connecting real and imaginary parts of elastic scattering amplitudes and formally valid at any energy above the physical threshold. By means of fits to total cross section data from proton-proton and antiproton-proton scattering, we evaluate the corresponding ratio ρ between the real and imaginary parts of the forward amplitudes. We show that the results are exactly the same as those obtained through standard integral dispersion relations.

Detailed Application

This paper comprises the first detailed application of the microscopic potentials for a simultaneous analysis of the elastic scattering and fusion cross-section data of the 12 C+ 24Mg system from 16.0 MeV to 24.0 MeV. We use the microscopic nucleon-nucleon double folding and α-α double folding cluster potentials within the framework of the optical model and coupled-channels formalism. We compare our microscopic potential results with the findings of the phenomenological deep and shallow potentials. All potentials provide a very good agreement with the experimental data for the elastic scattering angular distributions. However, only deep phenomenological, the microscopic nucleon-nucleon and α-α double folding cluster potentials provide a consistent description of the angular distributions and fusion cross-section data simultaneously.

The Impact

In today’s cross section data processing process, asymptotic scattering model is employed by NJOY for the neutron/nucleus elastic scattering interactions in the epithermal energy region, which means that the energy of a scattered neutron is always lower than its incident energy and it falls evenly within the interval of [αE, E]. This model has recently been proved to have non-ignorable errors at some resonances of heavy nuclides. In this study, to investigate the impact of heavy nuclides resonance elastic scattering models to the resonance integrals, exact scattering kernel is employed and a deterministic code Estuary is developed to efficiently solve the neutron slowing down problem. Numerical results demonstrate that with the use of Estuary, results given in the literature obtained by the Monte Carlo method can be reproduced. With the resonance cross section approximately represented by the single-level Breit-Wigner formulation, investigations are made for different resonance parameters for both asymptotic and exact scattering models. Relations between errors and these related parameters are summarized.

Shift Model

We have used the computer language Java to develop a computer simulation program for heavy-ion elastic scattering based on the parameterized phase shift model. Using this program, we have carried out a χ2-fit to the observed differential cross-section data of the heavy-ion elastic scattering and performed computer simulations of the angular distribution, the deflection function, the reaction cross-section, the scattering matrix element, and the analysis results as graphical representations. The program is also applied to elastic scattering of the 12C+12C system at E lab = 1016 MeV.
