Application of the H-N method to the critical slab problem for reflecting boundary conditions
(Pergamon-Elsevier Science Ltd, 2004)The recently developed H-N method is used to solve the critical slab problem for a slab which is surrounded by a reflector. In the special case: for R = 0 (the reflection coefficient) the problem reduces to the one under ... -
Comparison of fission barrier and level density models for (alpha,f) reaction of some heavy nuclei
(Pergamon-Elsevier Science Ltd, 2014)In this work, alpha induced fission reactions for some heavy nuclei (Th-232, U-235, U-238, Np-237 and Pu-238) are calculated based on both fission barrier models and level density models by using the TALYS 1.2 code. The ... -
Effects of thermal and deformation on martensitic transformation and magnetic properties in Fe-17%Mn-4.5%X (X = Co and Mo) alloys
(Pergamon-Elsevier Science Ltd, 2017)In this study, the Co and Mo addition to Fe-Mn based alloys was investigated to observe its effect on martensitic phase transformation. Two types of martensite structure occurred from the surface observations made by SEM ... -
Electron paramagnetic resonance of gamma-irradiated single crystals of 3-nitroacetanilide
(Pergamon-Elsevier Science Ltd, 2008)The electron paramagnetic resonance of single crystals of 3-nitroacetanilide has been observed and analyzed for different orientations of the crystal in the magnetic field, after being damaged at 300 K by gamma-irradiation. ... -
Equilibrium and pre-equilibrium calculations of neutron production in medium-heavy targets irradiated by protons up to 100 MeV
(Pergamon-Elsevier Science Ltd, 2008)In this study, by using equilibrium and pre-equilibrium reaction mechanisms, the (p,xn) cross-sections of the spallation neutron target nuclei Cr-50,Cr-52,Cr-53,Cr-54 and Cu-63,Cu-65 were investigated for incident proton ... -
The HN method for half-space Albedo and constant source problems for isotropic and anisotropic scattering kernels
(Pergamon-Elsevier Science Ltd, 2007)The H-N method, which is developed recently, is used to solve the half-space albedo and the half-space constant source problems for both isotropic and extremely anisotropic scattering kernels. It has been shown that the ... -
Investigation of the nuclear structure of the Be, Cr and Cu isotopes
(Pergamon-Elsevier Science Ltd, 2009)The Root-Mean-Square (RMS) nuclear charge, neutron and proton radii, charge, neutron and proton densities, neutron skin thickness and total binding energy per particle were calculated using the Hartree-Fock method with ... -
Investigation of the properties of the nuclei used on the new generation reactor technology systems
(Pergamon-Elsevier Science Ltd, 2008)The main application fields of the fast neutrons are accelerator-driven subcritical systems (ADS) and fusion-fission (hybrid) reactor systems for fission energy production. Thorium (Th) and uranium (U) are nuclear fuels ... -
Level density parameter dependence of the fission cross sections of some subactinide nuclei induced by protons with the incident energy up to 250 MeV
(Pergamon-Elsevier Science Ltd, 2009)This study aims to show the dependence on the choice of the ratio of the level density parameters a(f) and a(n) corresponding to the saddle point of fission and equilibrium deformation of nucleus, respectively, of the ... -
Monte Carlo studies in accelerator-driven systems for transmutation of high-level nuclear waste
(Pergamon-Elsevier Science Ltd, 2008)A spallation neutron source was modeled using a high energy proton accelerator for transmutation of Pu-239, minor actinides Np-237, Am-241 and long-lived fission products Tc-99, I-129, which are created from the operation ... -
