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, ...
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 ...
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 ...
Investigation of some even-even selenium isotopes within the interacting boson model-2
(Versita, 2008)
The even-even Selenium isotopes in the A similar to 80 mass region and the general features of its structure have been investigated within the framework of the interacting boson model-2. The neutron proton version of the ...
Spherical albedo problem for isotropic scattering
(Carl Hanser Verlag, 2008)
The pseudo-slab problem by using the H-N method, proper neutron flux definitions and physical boundary conditions is used to study spherical albedo. The selected numerical values can be compared with data available in the ...
N-(p-chlorophenyl)-3,3-diphenyl-4-(β-phenylstyryl)azetidin-2-one
(Munksgaard Int Publ Ltd, 2000)
In the title compound, C35H26ClNO, the four-membered beta-lactam ring is essentially planar, with a maximum deviation of 0.012 (1) Angstrom for the N atom. The C-C bond lengths in the beta-lactam ring are 1.591 (2) and ...
