Spontaneous fission of neutron-deficient fermium isotopes and the new nucleus 241Fm
The neutron-deficient fermium isotopes with A≤244 were produced by the fusion-evaporation reactions of 40 Ar projectiles and targets of 204,206-208 Pb [1]. Only spontaneous fission (SF) half-life of (3.12±0.08) ms. We deduced an upper limit of 0.01 and 0.02 for the α and EC branching of 244 Fm. The isotope 243 Fm was produced in the reaction 40 Ar+ 206 Pb→ 243 Fm+3n, and an excitation function ...
متن کاملMonte Carlo Hauser-Feshbach Modeling of Prompt Fission Neutrons and Gamma Rays
The decay of fission fragments is studied through Monte Carlo Hauser-Feshbach model calculations taking into account the competition between the emissions of prompt fission neutrons and gamma rays. The importance of initial excitation energy and spin distribution in the primary light and heavy fragments is demonstrated through comparison with experimental data. Excitation energy sorting mechani...
متن کاملTagging fast neutrons from a 252Cf fission-fragment source.
Coincidence and time-of-flight measurement techniques are employed to tag fission neutrons emitted from a 252Cf source sealed on one side with a very thin layer of Au. The source is positioned within a gaseous 4He scintillator detector. Together with α particles, both light and heavy fission fragments pass through the thin layer of Au and are detected. The fragments enable the corresponding fis...
متن کاملthe effect of traffic density on the accident externality from driving the case study of tehran
در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولThe “higgs” from Anti-neutrons and Neutrons
The new anti-neutron, first proposed in 2011 [16], and ordinary neutrons, are both without electric charge, and are therefore rather difficult to accelerate and/or impact together in a high energy collider sufficient to cause annihilation, and thus create a 100% energy “Higgs” styled Boson, such Bosons arguably representing all of the mass in the universe. This very high energy impact combinati...
