Surface Effect In Explaining The Elastic Scattering Of The $\Alpha +^{12}$C System At Low Energies, Yasemi̇n Küçük
Surface Effect In Explaining The Elastic Scattering Of The $\Alpha +^{12}$C System At Low Energies, Yasemi̇n Küçük
Turkish Journal of Physics
In this paper, the elastic scattering angular distributions data of the $\alpha +$12C reaction at an energy range of 13.0 to 172.5 MeV were analyzed within the framework of optical model formalism. A phenomenological deep real potential was used with a phenomenological Woods-Saxon type imaginary potential. Excellent agreement was obtained in the high-energy region. The phenomenological deep potential was unable to explain the experimental data in the low-energy region. The experimental data at both low and high energies could not be explained at the same time. In order to explain the data simultaneously at low energy and high energy, the …
Elastic Scattering Analysis Of $^{12}$C+$^{24}$Mg By Wkb Method, Orhan Bayrak
Elastic Scattering Analysis Of $^{12}$C+$^{24}$Mg By Wkb Method, Orhan Bayrak
Turkish Journal of Physics
We present the elastic scattering analysis of the $^{12}$C+$^{24}$Mg system by using the WKB approximation method within the framework of the barrier-internal wave decomposition over a wide range of energy from E$_{lab}$ = 16 MeV to 24.0 MeV. The results obtained are good agreement with the quantum mechanical (QM) calculation and experimental data.
A Study On $^{7}$Li + $^{120}$Sn Quasi-Elastic Scattering, Murat Aygün, Zeynep Aygün
A Study On $^{7}$Li + $^{120}$Sn Quasi-Elastic Scattering, Murat Aygün, Zeynep Aygün
Turkish Journal of Physics
In the present study, we reexamine quasi-elastic scattering of $^{7}$Li by $^{120}$Sn 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.
A Full Relativistic Treatment In Analyzing $\Alpha $-$^{12}$C And $\Alpha $-$^{40,42,44,48}$Ca Elastic Scattering Data At 1.37 Gev, Zuhair Fayyad Mahmoud Shehadeh
A Full Relativistic Treatment In Analyzing $\Alpha $-$^{12}$C And $\Alpha $-$^{40,42,44,48}$Ca Elastic Scattering Data At 1.37 Gev, Zuhair Fayyad Mahmoud Shehadeh
Turkish Journal of Physics
A simple optical potential of Woods-Saxon form is used within the framework of the Klein-Gordon equation, for the first time, to analyze the elastic differential cross sections for 1.37 GeV (lab) incident $\alpha $-particles on $^{12}$C and calcium isotopes $^{40,42,44,48}$Ca. The relativistic energy-momentum relation assures the need for relativistic calculations. As such, the previously determined parameters of all optical potential forms, used in the nonrelativistic Schrödinger equation and successfully analyzing the $\alpha $-$^{12}$C and $\alpha $-$^{40,42,44,48}$Ca data at 1.37 GeV, are to be revised. In the presence of Coulomb potential, as in the cases under consideration, the asymptotic solution of …
Analyses Of Elastically Scattered Charged Pions From Calcium Isotopes And The ^{48}Ca-^{54}Fe Isotone At 180 Mev, Zuhair Fayyad Mahmoud Shehadeh
Analyses Of Elastically Scattered Charged Pions From Calcium Isotopes And The ^{48}Ca-^{54}Fe Isotone At 180 Mev, Zuhair Fayyad Mahmoud Shehadeh
Turkish Journal of Physics
The elastic scattering of 180 MeV positively and negatively charged pions, incident on a set of calcium isotopes and the isotone ^{48}Ca - ^{54}Fe, has been analyzed within the framework of a recently updated simple local optical potential. This potential, particularly at the tail region, has been originally determined from available phase shifts using inverse scattering theory and the Klein--Gordon equation as a guide. The analysis is carried out with and without considering the squared potential term in the Klein-Gordon equation. Coulomb effects are accounted for by implementing Stricker's prescription. The numerical results for the angular distributions with isotopic and …
