$3d$-electrons contribution to cohesive energy of $3d$-metals [PDF]

, 2018
In this paper a model for $3d$-subsystem of transition $3d$-metals has been proposed and used for calculation of the cohesive energy dependent on $3d$-band filling of particular metal, its bandwidth and effective intra-atomic interaction value.

Astrophysical SE2 factor of the 12C(α, γ)16O reaction through the 12C(11B, 7Li)16O transfer reaction

EPJ Web of Conferences, 2016
The 12C(α, γ)16O reaction plays a key role in the evolution of stars with masses of M > 0.55 M⊙. At the Gamow peak (Ec.m. = 300 ke V, T9 = 0.2), the cross section of the 12C(α, γ)16O reaction is so small (about 10−17 barn) that the direct measurement in ...

Energy partitioning for “fuzzy” atoms [PDF]

The Journal of Chemical Physics, 2004
The total energy of a molecule is presented as a sum of one- and two-atomic energy components in terms of “fuzzy” atoms, i.e., such divisions of the three-dimensional physical space into atomic regions in which the regions assigned to the individual atoms have no sharp boundaries but exhibit a continuous transition from one to another.

Progress in Chlorination and Dissolution Technology of Oxides of Uranium and Plutonium

He huaxue yu fangshe huaxue, 2022
The dissolution process of oxides is a key step in the pyrochemical process of spent oxide fuel by electrolyzing in molten salt. The dissolved products will provide feeds for subsequent separation and recovery of U and Pu.

Development of active neutron nondestructive assay system [PDF]

EPJ Web of Conferences
The assay of Special Nuclear Materials (SNM) and Minor Actinides (MA) in highly-radioactive nuclear materials poses a significant challenge for nuclear non-proliferation and security. No single nondestructive method can provide acceptable and practicable

Extraction of Uranium From Alkali Residue With Supercritical Carbon Dioxide Fluid

He huaxue yu fangshe huaxue, 2023
Alkali residue was dissolved by the ammonium hydrogen fluoride method, in which the uranium content is determined to be (16.7±0.3)%(n=6) by inductively coupled plasma optical emission spectrometry(ICP-AES).
