Mossbauer studies on athermal martensite formation in an Fe-Ni-Mn alloy
(Indian Academy Sciences, 2002)
In this study, austenite-martensite phase transformations which are formed by cooling effect in Fe-30% Ni-0.2% Mn alloy are investigated with Mossbauer spectroscopy and scanning electron microscopy. The single peak of the ...
Calculations of Double-Differential Neutron Emission Cross Sections for Be-9 Target Nucleus at 14.2 MeV Neutron Energy
(Springer, 2015)
In this study, we investigated neutron-emission spectra induced by (n,xn) nuclear reactions for the Be-9 structural fusion material at 14.2 MeV neutron energy. We calculated double-differential cross sections () with ...
(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 ...
Calculations of proton-induced neutron production cross sections on Th-232 up to 1.6 GeV
(Amer Nuclear Society, 2006)
The Th-232(p, xn) and Th-232(p, np) cross sections for incident proton energies in the range of 10 to 1600 MeV have been calculated by using a cascade-exiton model (CEM) combining essential features of the exciton model ...
(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 ...
Calculations of double-differential triton emission cross sections at 62-MeV proton-induced reactions
(Pleiades Publishing Inc, 2014)
Double-differential cross sections (d (2) sigma/d Omega dE >) have been calculated and analyzed for triton production in proton-induced reactions on Al-27, Fe-54,Fe-56, Au-197, and Pb-208 target nuclei at incident energy ...
Pre-equilibrium Emission Spectra Calculations of Th-232(n,xn) Using New Evaluated Method
(Springer, 2011)
The knowledge of the thorium (Th-232) cycle potentialities are required for the design of a fusion-fission (hybrid) reactor. Pre-equilibrium nuclear reactions have been used to investigate the effect of initial exciton ...
The effect of the initial exciton numbers on Fe-54,Fe-56(p, xp) Pre-Equilibrium Reactions
(Maik Nauka/Interperiodica/Springer, 2011)
In pre-equilibrium nuclear reactions, the geometry-dependent hybrid model is applied with the use of the neutron and proton densities to investigate the effect of initial exciton numbers on the nucleon emission spectra. ...
New calculation method for initial exciton numbers on nucleon induced pre-equilibrium reactions
(Amer Physical Soc, 2008)
In this study, we investigate the pre-equilibrium effect by using new evaluated geometry dependent hybrid model for the 208 Ph (p, xn) reaction at 25.5 and 62.9 MeV incident proton energies. We also suggest that the initial ...
A Study on Be8-18 Isotopes Used on Neutron Multiplier in Reactor Design
(Springer, 2011)
Neutronic characterization and development of structural materials, neutron multiplier materials, tritium breeders are primarily important for fusion and hybrid reactors. In order to improve neutron economy, beryllium, ...
