Beyond-mean-field dynamical correlations for nuclear mass table in deformed relativistic Hartree-Bogoliubov theory in continuum

Chinese Physics C, High Energy Physics & Nuclear Physics, 2022
We extend the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) to go beyond-mean-field framework by performing a two-dimensional collective Hamiltonian.

Considerations about a microscopic description of the α-particle decay of heavy nuclei

, 1980
A particle decay theory is formulated for long-lived states where the decay is determined by the knowledge of the bound-state wavefunction of the metastable decaying nucleus. This theory is especially interesting for alpha -decaying states.

Nuclear Data Uncertainty Propagation for the Molten Salt Fast Reactor Design

Nuclear science and engineering, 2023
The development of new reactor technologies requires careful assessments of the various sources of epistemic uncertainties. In this work, nuclear data uncertainties featuring the main isotopes of the U/Th molten salt fast reactor (MSFR) design are ...

Elucidating Actinide-Pertechnetate and Actinide-Perrhenate Bonding via a Family of Th-TcO4 and Th-ReO4 Frameworks and Solutions.

Inorganic Chemistry, 2023
Technetium-99, a β-emitter produced from 235U fission, poses a challenge for the nuclear industry due to co-extraction of pertechnetate (TcO4-) with the actinides (An) during nuclear fuel reprocessing.

Nuclear mass predictions of the relativistic continuum Hartree-Bogoliubov theory with the kernel ridge regression

Physical Review C
Background: Nuclear masses are of fundamental importance in both nuclear physics and astrophysics, and the masses for most neutron-rich exotic nuclei are still beyond the experimental capability.

Prediction of nuclear clock transition frequency difference between 229Th3+ and 229Th4+ via ab initio self-consistent field theory

Science China Physics, Mechanics & Astronomy
The $^{229}\text{Th}$ isotope is a promising candidate for nuclear clocks, with its transition frequency influenced by electron-induced nuclear frequency shifts. This effect is comparatively small and requires high-precision theoretical calculations.

Substantial Nuclear Hyperfine Mixing Effect in Boronlike ^{205}Pb Ions.

Physical Review Letters
Nuclear hyperfine mixing (NHM) is a distinctive effect through which nuclear properties and dynamics can be efficiently controlled. Traditionally, the scientific consensus has predominantly associated NHM with its pronounced impact on ^{229}Th, owing to ...
