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 ...

Proton elastic scattering from the chromium isotopes
Nuclear Physics, 1964Abstract Differential cross-sections for protons elastically scattered from isotopic chromium targets have been measured using semiconductor counters. The data obtained have been analysed using an optical model parameter search programme. The observed variation of the proton parameters with isotope is discussed.

Journal of Geophysical Research: Solid Earth
AbstractThe stable chromium isotope system has been widely used as a redox proxy to reconstruct the oxygenation history of ocean atmosphere systems. However, the Cr isotope mass balance in modern oceans (i.e., inputs and outputs) remains poorly constrained.

Chromium isotopic anomalies in the Murchison meteorite
Earth and Planetary Science Letters, 1989Abstract The abundances of chromium isotopes, in refractory inclusions from the Allende meteorite, show wide-spread anomalies. The chromium isotope anomalies are similar in pattern to the anomalies discovered in calcium and titanium. The largest effects occur at the neutron-rich isotopes 48 Ca, 50 Ti and 54 Cr.

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.
