Laser isotope separation of 223Ra

open access: yesScientific Reports, 2023
A three-step photoionization has been theoretically studied for the laser isotope separation of 223Ra through the following photoionization scheme. $$\begin{aligned}7s^{2} {}^{1}S_{0} \left( {0.0 \;{\text{cm}}^{ - 1} } \right)\xrightarrow{{714.3185 ...

Sum Rule Approach to the Isoscalar Giant Monopole Resonance in Drip Line Nuclei [PDF]

open access: yes, 2005
Using the density-dependent Hartree-Fock approximation and Skyrme forces together with the scaling method and constrained Hartree-Fock calculations, we obtain the average energies of the isoscalar giant monopole resonance. The calculations are done along

Theoretical study of elastic electron scattering off stable and exotic nuclei [PDF]

open access: yes, 2008
Results for elastic electron scattering by nuclei, calculated with charge densities of Skyrme forces and covariant effective Lagrangians that accurately describe nuclear ground states, are compared against experiment in stable isotopes.

Analysis of bulk and surface contributions in the neutron skin of nuclei [PDF]

open access: yes, 2010
The neutron skin thickness of nuclei is a sensitive probe of the nuclear symmetry energy having multiple implications for nuclear and astrophysical studies. However, precision measurements of this observable are difficult.

ON THE GF-VALUES FOR SOME DIATOMIC MOLECULAR SPECTRA

open access: yesOdessa Astronomical Publications, 2017
In view of rich structure of the energy levels and the variety of transition types which are observable, molecules are the useful tool for investigation of physical parameters of stellar atmospheres, interstellar and circumstellar matter.

Ground-state properties and symmetry energy of neutron-rich and neutron-deficient Mg isotopes [PDF]

open access: yes, 2014
A comprehensive study of various ground-state properties of neutron-rich and neutron-deficient Mg isotopes with $A$=20-36 is performed in the framework of the self-consistent deformed Skyrme-Hartree-Fock plus BCS method.

Kinetic and Metabolic Isotope Effects in Zooxanthellate and Non-zooxanthellate Mediterranean Corals Along a Wide Latitudinal Gradient

open access: yesFrontiers in Marine Science, 2019
Many calcifying organisms exert significant biological control over the construction and composition of biominerals which are thus generally depleted in oxygen-18 and carbon-13 relative to the isotopic ratios of abiogenic aragonite. The skeletal δ18O and

Trophic Diversity and Food Web Structure of Vegetated Habitats Along a Coastal Topographic Gradient

open access: yesFrontiers in Marine Science, 2022
Land–sea interactions in coastal wetlands create heterogeneous vegetated habitats with regular zonation along a topographic gradient. However, it’s unclear how the trophic diversity of communities and trophic structure of food webs change along the ...

Effect of habitat degradation on competition, carrying capacity, and species assemblage stability [PDF]

open access: yes, 2017
In human-impacted rivers, nutrient pollution has the potential to disrupt biodiversity organisation and ecosystem functioning, prompting calls for effective monitoring and management.

Supernova Reverse Shocks and SiC Growth [PDF]

open access: yes, 2003
We present new mechanisms by which the isotopic compositions of X-type grains of presolar SiC are altered by reverse shocks in Type II supernovae. We address three epochs of reverse shocks: pressure wave from the H envelope near t = 10$^6$s; reverse ...
