Öğe Calculation of Fission Barrier of 230-234Pa Isotopes(Azerbaijan Journal of Physics - Fizika, 2010) Yılmaz, Ahmet Hakan; Engin, B.; Bayram, Tuncay; Demirci, M.The fission barriers of 230-234Pa have been carried out by using the BARRIER code developed by Garcia. The nuclear shape has been parameterized in terms of Cassini ovaloids proposed by Pashkevich. The single- particle energies have been calculated as function of the deformation parameters of an axially deformed Woods-Saxon potential, as input to the shell correction calculations. To obtain the total nuclear energy, it is also necessary to add a pairing energy in order to take into consideration the short range nuclear interactions.Öğe Ground State Nuclear Properties of Some Rare Earth Nuclei in Relativistic Mean Field Theory(Azerbaijan Journal of Physics - Fizika, 2010) Yılmaz, Ahmet Hakan; Bayram, Tuncay; Demirci, M.; Engin, B.In this study, rare earth nuclei, 160Gd, 168Er , 170Er and isotopic chain of Dy were investigated using relativistic mean field theory with non-linear NL3 and NLSH parameters sets. Binding energies per nucleon, neutron radii, proton radii, charge radii, neutron and proton quadrupole moments of these nuclei were calculated. Also, these ground state properties were calculated using non-relativistic Hartree-Fock-Bogoliubov method with parameters set SKP. Predictions of this work were compared with available experimental data and some predictions calculated with different parameters set in relativistic mean field theory.Öğe Ground State Nuclear Propertıes Of Mo And Ru Isotopes In Skyrme-Hartree-Fock-Bogolıubov Method(Balkan Physics Letters, 2011) Bayram, Tuncay; Yılmaz, Ahmet Hakan; Engin, B.; Demirci, M.Ground-state nuclear properties of Mo and Ru isotopes were studied within the Hartree-Fock-Bogoliubov method with SL y4 and SL y5 Skyrme forces. Nuclei which have neutron numbers close to magic number 50 have received much attention because the nuclei are known well deformed and exhibit anomalous behaviour in the isotope shifts. Therefore, a systematic study of even-even Mo and Ru isotopes was carried out. Almost all ground-state properties which include binding energy per nucleon, quadrupole deformation, nuclear radii, two -neutron separation energyand shape-coexistence for axially deformed Mo and Ru isotopes were analyzed. The results were compared with available experimental data and predictions of some nuclear models (Finite Range Liquid-Drop Model (FRDM), Extended Thomas Fermi Model with Strutinski Integral (ETF-SI) and Relativistic Mean Field (RMF) Theory) and discussed in detail. The results show that the HFB method with SLy4 and SL y5 Skyrme forces is capable of describing of isotopic chain of even-even Mo and Ru nuclei.Öğe Ground-State Properties of Axially Deformed Sr Isotopes in Skyrme-Hartree-Fock-Bogoliubov Method(Azerbaijan Journal of Physics - Fizika, 2010) Yılmaz, Ahmet Hakan; Bayram, Tuncay; Demirci, M.; Engin, B.Binding energies, the mean-square nuclear radii, neutron radii, quadrupole moments and deformation parameters to axially deformed Strontium isotopes were evaluated using Hartree-Fock-Bogoliubov method. Shape coexistence was also discussed. The results were compared with experimental data and some estimates obtained within some nuclear models. The calculations were performed for Sly4 set of Skyrme forces and for a wide range of the neutron numbers of Sr isotopes.
