Using a clinical linac to determine the energy levels of (92m)Nb via the photonuclear reaction.

The bremsstrahlung photons of 18MeV end-point energy produced by a clinical linear accelerator were used to irradiate (93)Nb, producing (92m)Nb via the photonuclear reaction. The gamma-ray spectrum emitted by the excited nucleus was measured with high purity germanium detector. For analysis of the energy transitions, both gf3 and ROOT spectrum analysis programs were applied. The results were shown to be comparable with the literature values, demonstrating the ability to use a clinical liner accelerator in nuclear physics measurements.

A study on the Fresnel diffraction of 6He by means of different microscopic density distributions

The elastic scattering of the halo nucleus 6He from heavy targets such as 197Au and 208Pb has been investigated in order to explain the Coulomb rainbow peak due to the Fresnel-type diffraction observed in the experimental data. In order to examine the role of nuclear potential to describe 6He + 197Au and 6He + 208Pb systems, we have used the no-core shell model, few-body and Gaussian-shaped density distributions at various energies. The microscopic real parts of the complex nuclear potential have been obtained by using the double-folding model for each of the density distribution and the phenomenological imaginary potentials have been taken as the standard Woods-Saxon shape. We have observed that fewbody and Gaussian-shaped density distributions have given standard Fresnel-type diffraction results, a classical scattering pattern with Coulomb rainbow peak whereas the nuclear potential obtained by using the no-core shell-model density distribution has provided the reduction at Fresnel peak and has given more consistent results with the experimental data.

A study on 7Li + 120Sn quasi-elastic scattering

In the present study, we reexamine quasi-elastic scattering of 7Li by 120Sn at incident energies E Lab = 19.5, 20.5, and 25.0 MeV. The theoretical results are obtained by using both a phenomenological model and double-folding model (DFM) within the framework of an optical model. We also investigate the role of the surface potential, which is connected to direct reactions. The agreement between the phenomenological model and the DFM is shown in comparison to each other in connection with the experimental data. This comparison provides information about the similarities and the differences between the models used during the calculations.

Analysis of molecular, Woods-Saxon and squared Woods-Saxon potentials on 7Be elastic scattering by 10B, 14N, and 208Pb

The angular distributions of elastic scattering of 7Be projectile from 10B, 14N, and 208Pb have been reanalyzed. In this context, for the first time, the molecular potential has been applied to obtain nuclear potential within the optical model. Then, the theoretical calculations have been repeated by using the Woods-Saxon and Squared Woods-Saxon potentials. All the theoretical results have been compared with each other as well as the experimental data.
