We elucidated the reason why average total kinetic energy (TKE) of fission fragments decreases when excitation fissioning systems increases as indicated by experimental data for neutron-induced events. To explore this problem, we used a method based on four-dimensional Langevin equations have developed. calculated TKE $^{236}$U$^{*}$ and $^{240}$Pu$^{*}$ excited above respective barriers, compa...

A model based on the macroscopic-microscopic approach for calculating the fission-fragment properties is presented. Using this model, a large set of experimental data measured in lowand high-energy fission can be reproduced using one and same set of model parameters.

Numerical computations of transport coefficients at low temperatures are presented for shapes typically encountered in nuclear fission. The influence of quantum effects of the nucleonic degrees of freedom is examined, with pair correlations included. Consequences for global collective motion are studied for the case of the decay rate. The range of temperatures is specified above which this moti...

the radiophotoluminescence property of some materials makes it possible to use them for dosimetry purposes. the silver activated metaphoshate glass 1 as an rpl dosimeter when exposed to x. or y radiations , forms fluorescent centers with long lived states ( metastate ). the silver ions (ag+) in unirradiated state produces vacancies when energy is supplied by irradiation the release of electrons...

One of the outcomes electrospray ionization is size distribution droplets, which determines, together with solvent composition and source gas temperature, minimum distance from sprayer tip to mass spectrometer inlet therefore ion transfer efficiency. Even more importantly, average number analyte molecules and, if present, contaminant species per droplet depend on drop size. Consequently, a key ...

In order to improve on current prompt fission neutron spectrum measurements, a gamma multiplicity tagging method was developed at the Rensselaer Polytechnic Institute Gearttner Linear Accelerator Center. This method involves using a coincidence requirement on an array of BaF2 gamma detectors to determine the timing of a fission event. This allows for much larger fission samples to be used due t...

Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...

With the improved scission-point model mass distributions are calculated for induced fission of Hg isotopes with even mass numbers A = 174 – 198. The calculated mass distributions and mean total kinetic energy of fission fragments are in good agreement with the existing experimental data. The asymmetric mass distribution of fission fragments of 180Hg observed in the recent experiment is explain...

The impact of dynamic pairing correlations and their interplay with Coulomb antipairing effects on the systematic spontaneous fission half-lives for nuclei $^{240-250}$Cm $^{240-250}$Cf is analyzed, using a hierarchy approximations based parametrization D1M Gogny energy density functional (EDF). First, constrained Hartree-Fock-Bogoliubov (HFB) approximation used to compute deformed mean-field c...
