Ab initio search for global minimum structures of neutral and anionic hydrogenated Li-5 clusters
(Elsevier Science Bv, 2013)
The structure and some electronic properties of neutral and anionic Li5Hn (n = 0-6) clusters have been studied by using the stochastic search method with the B3LYP/6-31G level of theory. After searching possible isomers, ...
(γ,2n) Reaction Cross Section Calculations on Several Structural Fusion Materials
(Springer, 2013)
In this study, the theoretical photo-neutron cross-sections produced by (gamma,2n) reactions for several structural fusion materials such as V-51, Mn-55, Ni-58, Zr-90,Zr-91,Zr-92,Zr-94, and Ta-181 have been carried out for ...
Experimental and theoretical approaches on mechanical evaluation of Y123 system by Lu addition
(Springer, 2013)
This work is the continuation of a systematic study on the characterization of the Lu-added Y123 bulk superconducting materials prepared by the nitrate compounds and derivatives at 970 degrees C for 20 h. In this part, the ...
Pre-equilibrium neutron-emission spectra of U-238 with an effective nucleon-nucleon interactions
(Pergamon-Elsevier Science Ltd, 2013)
In this study, the initial exciton numbers for the target nucleus U-238 were calculated through a new method offered by Tel et al. (Ann. Nucl. Energy, 35, 220, 2008). Neutron-emission spectra produced by (n,xn) reactions ...
(p,α) Reaction Cross Sections Calculations of Fe and Ni Target Nuclei Using New Developed Semi-empirical Formula
(Springer, 2013)
Iron (Fe) and nickel (Ni) are important fusion structural materials in reactor technology. The gas production in the metallic structure arising from many different types of nuclear reactions has been a significant damage ...
Silver and fluoride doped hydroxyapatites: Investigation by microstructure, mechanical and antibacterial properties
(Elsevier Sci Ltd, 2013)
Hydroxyapatite co-doped with Ag+ and F- ions was synthesized by the precipitation method and sintered at 1100 degrees C for 1 h. Samples were characterized by density, X-ray diffraction, Fourier transform infrared spectroscopy, ...
Investigation of Some Stellar Iron Group Fusion Materials for (n, p) Reactions
(Springer, 2012)
In this study, we present the results of a careful analysis of cross sections of some important iron (Fe) group target elements (20 a parts per thousand currency sign Za parts per thousand currency sign28) for astrophysical ...
Solving the constant source problem for the quadratic anisotropic scattering kernel using the modified F-N method
(Carl Hanser Verlag, 2012)
In this work, the F-N method with different numerical approximations is used to solve the constant source problem for the quadratic anisotropic scattering kernel. Casev eigenfimctions and the orthogonality relations of ...
