Shell model study of single-particle and collective structure in neutron-rich Cr isotopes [PDF]

, 2008
The structure of neutron-rich Cr isotopes is systematically investigated by using the spherical shell model. The calculations reproduce well the known energy levels for the even-even {sup 52-62}Cr and odd-mass {sup 53-59}Cr nuclei, and predict a lowering

Evidence for shape coexistence in 52Cr through conversion-electron and pair-conversion spectroscopy [PDF]

EPJ Web of Conferences, 2020
Electric monopole (E0) transitions are a highly sensitive probe of the charge distribution of an atomic nucleus. A large E0 transition strength (ρ2(E0)) is a clear indicator of nuclear shape coexistence.

Ab Initio Phase Diagram of Chromium to 2.5 TPa

Applied Sciences, 2022
Chromium possesses remarkable physical properties such as hardness and corrosion resistance. Chromium is also a very important geophysical material as it is assumed that lighter Cr isotopes were dissolved in the Earth’s molten core during the planet’s ...

Redox reactions and the influence of natural Mn oxides on Cr oxidation in a contaminated site in northern Italy: evidence from Cr stable-isotopes and EPR spectroscopy

E3S Web of Conferences, 2013
Hexavalent chromium-contaminated groundwaters and sediments in northern Italy have been studied using the Cr stable-isotope systematics and electron spin resonance spectroscopy (ESR), in order to explore redox changes and soil-groundwater interactions ...

Passage kinetics of concentrates in dairy cows measured with carbon stable isotopes

Animal, 2013
Fractional passage rates form a fundamental element within modern feed evaluation systems for ruminants, but knowledge on feed-specific fractional passage is largely lacking. Commonly applied tracer techniques based on externally applied markers, such as

Petrogenesis and Geodynamic Implications of Late Triassic Mogetong Adakitic Pluton in East Kunlun Orogen, Northern Tibet: Constraints from Zircon U–Pb–Hf Isotopes and Whole-Rock Geochemistry

Frontiers in Earth Science, 2022
Adakites or adakitic rocks usually show special geochemical signatures and are petrological probes to reveal the tectono–magmatic evolutionary history of paleo–orogenic belts. Here, we present a comprehensive study on the zircon U–Pb geochronology, whole-

Global trends in novel stable isotopes in basalts: theory and observations

Goldschmidt2021 abstracts, 2021
The geochemistry of global mantle melts suggests that both mid-ocean ridge basalts (MORB) and ocean island basalts (OIB) sample lithological and temperature heterogeneities originating in both the upper and lower mantle.

Monitoring Cr toxicity and remediation processes - combining a whole-cell bioreporter and Cr isotope techniques [PDF]

Water Research, 2019
Bioremediation is a sustainable and cost-effective means of contaminant detoxification. Although Cr(VI) is toxic at high concentrations, various microbes can utilise it as an electron accepter in the bioremediation process, and reduce it to the less toxic form Cr(III).

Rapid cooling of planetesimal core-mantle reaction zones from Mn-Cr isotopes in pallasites

, 2016
Pallasite meteorites, which consist of olivine-metal mixtures and accessory phosphates crystallised from silico-phosphate melts, are thought to represent core-mantle reaction zones of early differentiating planetesimals.

Isotopic Evolution of the Inner Solar System Inferred from Molybdenum Isotopes in Meteorites [PDF]

Astrophysical Journal, 2020
The fundamentally different isotopic compositions of non-carbonaceous (NC) and carbonaceous (CC) meteorites reveal the presence of two distinct reservoirs in the solar protoplanetary disk that were likely separated by Jupiter.
