Exploring diffractive features of elastic scattering of ⁶Li by different target nuclei at different energies

Abstract

The diffractive aspects of angular distribution have been investigated by analyzing the experimental data for a set of elastic scattering processes of 6Li by different target nuclei at different laboratory energies. The analysis of experimental data of angular distribution for elastic scattering process is performed using both Frahn–Venter and McIntyre models. The theoretical models can reasonably reproduce the general pattern of the data, thus allowing us to extract geometrical parameters from elastic scattering processes. It is found that interpretation of the diffraction features of the data is model-independent. The values of extracted parameters, from both models, are found to be comparable to each other and to those of others. The correlation between the total reaction cross section and the incident laboratory energy for each scattering is discernible and values of total reaction cross section are found to be comparable with those of others.

Nickel-Hydrogen Cold Fusion by Intermediate Rydberg State of Hydrogen: Selection of the Isotopes for Energy Optimization and Radioactive Waste Minimization

“…This is a wavelike shape of the scattering cross-section as a function of scattering angle. Elastic scattering by Li nuclei provided by Badran and Al-Masri also show a similar wavelike shape dependence on the scattering angle, regarded by the authors as diffraction features[21].…”

“…As a result, a few complex models were developed using features of an optical model with a diffraction property and many adjustable parameters. In order to obtain an acceptable fitting to the data, Badran and D. Al-Masry [21] used even more elaborate models, some of them with 20 parameters (Table 4 of the article). It is understandable that in such approach with so many adjustable parameters any kind of scattering data could be fitted to the a priori concept of a small structureless spherical nucleus.…”

Cluster folding optical potential analysis for 6Li+28Si elastic scattering

“…The data at high energies [8][9][10][11][12][13][14] were also subjected to various optical model (OM) and DF analysis. The 6 Li + 28 Si system has been subjected to several theoretical studies [15][16][17][18][19][20][21] recently, which were devoted to investigating this nuclear system either at low and high energies using different pure OM and DF potentials. M. Anwar [17] analyzed the experimental angular distributions of 6 Li scattered elastically by different targets − 24 Mg, 28 Si, 40 Ca, 48 Ca, 58 Ni, 90 Zr, and 11 6Sn -at E lab ( 6 Li) = 240 MeV.…”

An Analysis of Heavy-Ion Elastic Scattering Processes Using Numerical Model Based on the Partial Wave Parameterised S-Matrix with Regge Pole Factor

“…This analysis will also allow the determination of several useful parameters and physical quantities, such as the grazing angular momentum Λ, the width of the ℓ-space window that contributes to elastic scattering, Δ, the nuclear phase shift, μ, the total reaction cross section σ r , etc. [17][18][19][20][21]. For an attempt to improve the fits and search for possibly existing Regge poles, which may be responsible for structures in the angular distribution, especially at backward angles, the numerical combined model will be employed using seven adjustable parameters (three SAM plus four Regge pole parameters) [17,31].…”
