Turkish Journal of Physics
The present work mainly purposed to investigate significant nuclear structure properties nuclei used in single photon emission computed tomography (SPECT), in addition to ground state nuclear properties such as the binding energy per particle, the root mean square (rms) charge, and proton and neutron radii. Besides, we calculated the neutron skin thicknesses (NST), the proton, neutron quadrupole moments ($Q_{P}, Q_{N})$, quadrupole deformation parameter ($\beta_{2})$, and the proton and neutron pairing energies ($P_{P}, P_{N})$ to determine shapes and deformations of SPECT nuclei including odd-odd or odd-even/even-odd nuclei in axial symmetry for Skyrme and Gogny interactions. To analyze the accuracy of the …

Lightest And Heaviest Two-Neutron Halo Nuclei, $^{6}$He And $^{22}$C, Waleed Hwash
Turkish Journal of Physics
The microscopic cluster model approach has been performed to study the nuclear structure of the lightest and heaviest two-neutron halo nuclei, $^{6}$He and $^{22}$C, respectively. The matter radius and binding energy for the $^{6}$He and $^{22}$C nuclei are calculated and the effect of the core deformation ($^{20}$C) on the properties of $^{22}$C nuclei is also discussed. Calculations have shown that the microscopic cluster model provides a good description of binding energy as well as matter radius in comparison to experimental data. The fittings of some parameters such as central potential depth (V$_{o})$, empirical constant (r$_{o})$, and surface diffuseness value (a) …
Properties Of Asymmetric Semiinfinite Nuclear Systems In The Extended Thomas-Fermi Model, Mohamed Abdalla
Properties Of Asymmetric Semiinfinite Nuclear Systems In The Extended Thomas-Fermi Model, Mohamed Abdalla
Turkish Journal of Physics
We start from the energy density of the Skyrme interaction and perform a leptodermous expansion for an asymmetric semiinfinite nuclear system. We get a liquid drop model formula for the energy of such a system. We use the obtained analytic formulae for volume, surface, and curvature energies to study the properties of asymmetric nuclear systems. We also study the effect of the asymmetry parameter on the volume, surface, and curvature properties.
Neutron-Rich ^{208}Pb Nucleus With Delta Excitation Under Compression, Mohammed Hassen Eid Abu-Sei'leek
Neutron-Rich ^{208}Pb Nucleus With Delta Excitation Under Compression, Mohammed Hassen Eid Abu-Sei'leek
Turkish Journal of Physics
The spherical Hartree-Fock approximation is applied to a no-core shell model with a realistic effective baryon-baryon interaction. The ground state properties of a heavy spherical neutron-rich doubly magic ^{208}Pb nucleus under compression are investigated. It is found that the nucleus becomes more bound with the occurrence of Delta resonances. The creation of Delta increases as the compression is continuous. There is a considerable reduction in the compressibility when the Delta degree of freedom is activated. It is found that the Delta particle is the basic component of the ^{208}Pb nucleus besides nucleons at the ground state without any compression. When …
Delta Excitation Calculation Studies In The Ground State Of The Compressed Finite Heavy Doubly-Magic Nucleus ^{100}Sn, Mohammed Hassen Eid Abu-Sei'leek
Delta Excitation Calculation Studies In The Ground State Of The Compressed Finite Heavy Doubly-Magic Nucleus ^{100}Sn, Mohammed Hassen Eid Abu-Sei'leek
Turkish Journal of Physics
The energies and matter densities of finite nuclei under radial compression are investigated by using a constrained Hartree-Fock method with the \Delta degree of freedom included. The results are presented for the doubly-magic nucleus ^{100}Sn in an effective baryon-baryon interaction. It is found that as the nucleus is compressed to about three time of the ordinary nuclear density, the \Delta component is sharply increased to about 17% of all baryons in the system. This result is consistent with the values extracted from relativistic heavy-ion collisions. The single particle energy levels calculated and their behaviors under compression examined too. A good …
