Analysis of Diffractive Features in Elastic Scattering of ~7Li by Different Target Nuclei at Different Energies

摘要

The diffractive features of angular distribution have been investigated by analyzing the experimental data for a set of elastic scattering processes of ~7Li by different target nuclei at different laboratory energies. Both Frahn-Venter and McIntyre models are used to analyze experimental data of angular distribution for elastic scattering processes. The theoretical models can reasonably reproduce the general pattern of the data. Some geometrical parameters for colliding nuclei have been obtained from the elastic scattering processes. It is found that interpretation of the diffractive features of the data is modelindependent. The values of extracted parameters, from adopted models, are found comparable to each other and to those of others. The total reaction cross section is correlated to the incident laboratory energy for each scattering and values of total reaction cross section are found comparable with those of others.
