New calculation for some ground state features of 40ca, 48ca 32s and 39k nuclei
(World Scientific Publ Co Pte Ltd, 2010)
Some ground states features of S-32, K-39, Ca-40 and Ca-48 nuclei are investigated using the Hartree-Fock method with the Skyrme SKM* and SLy4 forces calculated in two different code implementations. The calculated total ...
Improved Formula for (n,He-3) Fusion Reactions Cross Sections Using Optical Model
(Springer, 2010)
Non-elastic cross-sections have been calculated by using optical model for (n, He-3) reactions at 14-15 MeV energy. The new empirical formula including optical model non-elastic effects by fitting two parameters for the ...
Excitation Functions of Some Neutron Production Targets on (d,2n) Reactions
(Springer, 2010)
Deuterons are weakly bound nuclei which easily undergo break up reactions. This is well known at low energies, around 10 MeV, where deuteron beams have been used to produce neutrons very efficiently. These neutrons have a ...
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 ...
New Evaluated Semi-Empirical Formula Using Optical Model for 14-15 MeV (n, t) Reaction Cross Sections
(Springer, 2009)
In the next century the world will face the need for new energy sources. Nuclear fusion can be one of the most attractive sources of energy from the viewpoint of safety and minimal environmental impact. Fusion will not ...
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, ...
