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 ...
A Systematic Study Of Equilibrium And Pre-Equilibrium (P, N) Reaction Mechanisms Cross-Sections At Intermediate Energies For 25 < A < 240 Target Nuclei
(World Scientific Publ Co Pte Ltd, 2009)
In this present study, by using equilibrium and pre-equilibrium reaction mechanisms, the (p, n) cross-section values for some target (A = 25-240) nuclei were investigated in a range of 10-40 MeV incident energy. The ...
The Study of (n,d) Reaction Cross Sections for New Evaluated Semi-Empirical Formula Using Optical Model
(Springer, 2009)
Nuclear fusion can be one of the most attractive sources of energy from the viewpoint of safety and minimal environmental impact. The neutron scattering cross sections data have a critical importance on fusion reactor (and ...
Investigation of neutron skin effect with density dependence by using a new calculation method for initial exciton numbers on pre-equilibrium reactions
(Iop Publishing Ltd, 2009)
In this study, we investigated the pre-equilibrium effect by using a new evaluated geometry-dependent hybrid model and a neutron skin effect with density dependence for the (204,206,207)Pb(p, xn) reaction at 25.5MeV incident ...
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 ...
New calculations of excitation functions of some positron emitting and single photon emitting radioisotopes
(Carl Hanser Verlag, 2008)
In this study, new calculations of the excitation functions of (56)Fe(p,2n)(55)Co, (58)Fe(p,2n)(57)Co, (60)Ni(pn)(60)Ca, (62)Ni(p,2n)(61)Cu, (68)Zn (p,2n)(67)Ga, (72)Ge(p,n)(72)As, (82)Kr(p,2n)(81)Rb, (124)Xe(p,2n)(123)Cs, ...
Investigation of 14-15 MeV (n, t) reaction cross-sections by using new evaluated empirical and semi-empirical systematic formulas
(Springer, 2008)
In the hybrid reactor, tritium self-sufficiency must be maintained for a commercial power plant. For self-sustaining (D-T) fusion driver tritium breeding ratio should be greater than 1.05. Working out the systematics of ...
A new empirical formula for 14-15 MeV neutron-induced (n, p) reaction cross sections
(Iop Publishing Ltd, 2003)
In this study, we have suggested a new empirical formula to reproduce the cross sections of the (n, p) reactions at 14-15 MeV for the neutron incident energy. This formula obtained using the asymmetry parameters represents ...
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 ...
A New Comparison of Empirical and Semi-empirical Formulae for the (n, 3He) Reaction Cross-sections at 14–15 MeV
(Springer, 2008)
New empirical and semi-empirical formulae have been suggested for the (n, He-3) reaction cross-sections with dependent on asymmetry parameter, S = (N - Z)/A. The (n, He-3) reaction cross-sections at the energy of 14-15 MeV ...
