Chromium isotope systematics in the Connecticut River
Chemical Geology, 2017Abstract Limited constraints on Cr isotope fractionation during weathering and river transport is currently a gap in our understanding of the chromium (Cr) isotope system, which is an emerging proxy in environmental and paleoenvironmental studies. Here, we investigate Cr mobility and isotope fractionation from the temperate Connecticut River, USA ...

Isotope effect in chromium self-diffusion
Physical Review B, 1976The diffusion of $^{51}\mathrm{Cr}$ in chromium has been measured between 1100 and 1820\ifmmode^\circ\else\textdegree\fi{}C, and the data fit the Arrhenius relation $D=970\mathrm{exp}(\ensuremath{-}\frac{104000}{RT})$ ${\mathrm{cm}}^{2}$${\mathrm{sec}}^{\ensuremath{-}1}$.

Enrichment of chromium isotopes by gas centrifugation
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract Recently, chromium isotopes have been enriched using gas centrifuges that were developed by the United States Department of Energy for the purpose of enriching uranium in the fissionable isotope 235U. The process gas employed was chromyl-fluoride.

Chromium isotope fractionation in ferruginous sediments
Geochimica et Cosmochimica Acta, 2018Abstract Ferrous Fe is a potent reductant of Cr(VI), and while a number of laboratory studies have characterized Cr isotope fractionation associated with Cr(VI) reduction by ferrous iron, the expression of this fractionation in real-world ferrous Fe-rich environments remains unconstrained.

(3He, α) reactions on the chromium isotopes
Nuclear Physics A, 1969Abstract The reactions 50,52,53,54Cr(3He, α)49,51,52,53Cr have been studied at an incident energy of 18 MeV using a broad-range magnetic spectrograph as well as solid state detectors. Angular distributions were obtained for all isotopes. The relative isotopic cross sections were accurately determined by measurements with a target of mixed Cr isotopes.
