We have calculated the fission fragment angular anisotropy for 16O + 232Th,12C + 236U , 11B + 237 Np , 14 N + 232 Th , 11B + 235U , 12C + 232Th systems with the saddle point statistical model and compared the fission fragment angular anisotropy for these systems. This comparison was done with two methods a) without neutron correction and b) with neutron correction. Also we studied normal and ...
Fission of 238U nuclei was performed by 45-69 MeV protons at the Cyclotron and Radioisotope Center of Tohoku University in Japan. The fission products originated in the reaction were identified by using gamma spectroscopy. The experimental data show that the charge distribution of isobar fission products follows a Gaussian distribution with a standard deviation independent of the selected mass...
abstract uranium is a natural heavy metal widely dispersed across the earth crust. in many cases due to anthropogenic disturbance, it has been found beyond its natural abundance which resulted in soil-water pollution. the objective of this study was to investigate the capability of iranian natural zeolite clinoptilolite for removal of uranium (vi) from aqueous solutions. in order to optimize re...
The CAlifornium Rare Isotope Breeder Upgrade (CARIBU) is a new radioactive beam facility for the Argonne Tandem Linac Accelerator System (ATLAS). The facility utilizes a Cf fission source coupled with an electron cyclotron resonance (ECR) ion source to provide radioactive beam species for the ATLAS experimental program. The californium fission fragment distribution provides nuclei in the mid-ma...
The ALTO facility at IPN Orsay is based on a linear electron accelerator (50 MeV, 10μA) dedicated to the production of neutron rich radiactive beams by photofission of a thick uranium carbide target paced on an ISOL line. The construction of the facility has ended in december 2005 and the first on-line tests have been carried out in mid-2006. The production of fission fragments after separation...
abstract background : natural uranium exists in earth crust and seawater. the concentration of uranium might increase by human manipulation or geological changes. the aim of this study was to verify susceptibility of laser flourimetry method to determine the uranium concentration in caspian sea and persian gulf water. materials and methods : laser flourimetric method was used to determine t...
Nuclear fission produces 400 GWe which represents 11% of the global electricity output. Uranium is essential element as both fuel and radioactive waste. Therefore, recovery uranium great importance. Here, an in situ electrolytic deposition method to extract from aqueous solution reported. A functionalized reduced graphene oxide foam (3D-FrGOF) used working electrode, acts a hydrogen evolution r...
In this paper is presented a discussion of fission induced in heavy elements (uranium) by protons with kinetic energies below about 400 MeV with the main emphasis on fission with protons of a few hundred MeV energy *. Thus, reactions where meson interference becomes of any importance are not considered. Even if fission is the main reaction in heavy nuclei this can not be discussed without consi...
