Biogeochemical cycling of chromium and chromium isotopes in the sub-tropical North Atlantic Ocean

Frontiers in Marine Science, 2023
Chromium (Cr) is a redox-sensitive element and because Cr isotopes are fractionated by redox and/or biological processes, the Cr isotopic composition of ancient marine sediments may be used to infer changes in past seawater oxygenation or biological ...

Quadrupole Collectivity in Neutron-Rich Fe and Cr Isotopes

Physical Review Letters, 2013
Intermediate-energy Coulomb excitation measurements are performed on the N ≥ 40 neutron-rich nuclei (66,68)Fe and (64)Cr. The reduced transition matrix elements providing a direct measure of the quadrupole collectivity B(E2;2(1)(+) → 0(1)(+)) are determined for the first time in (68)Fe(42) and (64)Cr(40) and confirm a previous recoil distance method ...

Structure of the neutron-rich Cr isotopes

Journal of Physics G: Nuclear and Particle Physics, 2005
The low-lying levels in 59,60Cr have been populated with 13,14C(48Ca, 2p) reactions using a beam energy of 130 MeV. Prompt electromagnetic radiation was detected using the Gammasphere array, in coincidence with recoiling ions measured with the Fragment Mass Analyzer. The residues were selected and identified on the basis of charge-to-mass ratio, energy-

Ni target development for the TULIP project [PDF]

EPJ Web of Conferences, 2023
The TULIP project (https://anr.fr/Projet-ANR-18-CE31-0023) aims to produce radioactive ion beams of short-lived neutron-deficient isotopes using fusion-evaporation nuclear reactions in an Isotope Separator On Line (ISOL) system. A Ni target was chosen to

Interaction of primary precipitates in reduced -activation ferritic/martensitic steel F82H with hydrogen atoms: Atomistic calculation based on the density functional theory

Nuclear Materials and Energy, 2022
To understand the interaction of hydrogen isotopes with VC and Cr23C6 precipitates, in reduced-activation ferritic/martensitic steel (F82H), we have performed first-principles calculations based on density functional theory.

Effect of Chrome and Vanadium on the Behavior of Hydrogen and Helium in Tungsten

Mathematical and Computational Applications, 2023
Tungsten is a promising material for nuclear fusion reactors, but its performance can be degraded by the accumulation of hydrogen (H) and helium (He) isotopes produced by nuclear reactions.

Modeling the marine chromium cycle: new constraints on global-scale processes [PDF]

Biogeosciences, 2021
Chromium (Cr) and its isotopes hold great promise as a tracer of past oxygenation and marine biological activity due to the contrasted chemical properties of its two main oxidation states, Cr(III) and Cr(VI), and the associated isotope fractionation ...
