Strontium isotopes as an indicator of human migration – easy questions, difficult answers

Anthropological Review, 2015
Isotope analyses of bones and teeth allow us to study phenomena which occurred in the history of human species and which are difficult to capture by traditional anthropological methods. Measuring oxygen, nitrogen and carbon isotope levels in the skeleton

Strontium isotope (87Sr/86Sr) data from archaeological sites in Utah, USA

Data in Brief, 2019
The information presented here includes the results of strontium isotope analysis on 75 baseline samples from nine Fremont sites in Utah. The baseline samples are of lagomorphs and rodents with limited foraging ranges.

Cooling and trapping of ultracold strontium isotopic mixtures [PDF]

Physical Review A, 2005
We present the simultaneous cooling and trapping of an isotopic mixture in a magneto-optical trap and we describe the transfer of the mixture into a conservative, far-off resonant dipole trap. The mixture is prepared with a new technique that applies to intermediate and heavy alkaline earth like atoms.

The use of stable Cs and Sr as proxies for the estimation of radionuclide soil-plant transfer factors [PDF]

Ядерна фізика та енергетика
Transfer factors are key inputs for modelling the transport of radionuclides in the environment and for assessment of risk to humans and wildlife. However, for many combinations of soil conditions, plant species (products), and radionuclides, such ...

Strontium and oxygen isotopes to trace mobility routes during the Bell Beaker period in the north of Spain

Scientific Reports, 2021
Strontium and oxygen isotopes of individuals from El Hundido and Valdescusa (north of Spain) sites, corresponding to the Bell Beaker culture, were analysed in order to determine mobility patterns and provenance areas.

Strontium isotope and element constraints on the paleoenvironment of the latest Ediacaran in the Sichuan Basin, southeastern Tibetan Plateau

Frontiers in Earth Science, 2022
The Ediacaran–Cambrian period witnessed episodic extinctions, oxygenation of seawaters, Cambrian explosions, and tectonic events. However, compared with the various high-resolution geochemical records of the early–middle Ediacaran and Cambrian, the ...

Spectroscopic determination of the s-wave scattering lengths of 86Sr and 88Sr [PDF]

, 2005
We report the use of photoassociative spectroscopy to determine the ground state s-wave scattering lengths for the main bosonic isotopes of strontium, 86Sr and 88Sr.

⁸⁷Sr/⁸⁶Sr Isotope Ratio as a Tool in Archaeological Investigation: Limits and Risks

Quaternary
During the last forty years, the use of strontium isotopes in archaeology and biogeochemical research has spread widely. These isotopes, alone or in combination with others, can contribute to trace past and present environmental conditions.

Galgedil

Danish Journal of Archaeology, 2014
Galgedil is a Viking Age cemetery located in the northern part of the Danish island of Funen. Excavations at the site revealed 54 graves containing 59 inhumations and 2 cremation burials. Previous study of the remains to date has included light isotopes

Effect of Competing Ions on Multisorption (Cs+, Sr2+) by Composite Sorbents Based on Natural and Synthetic Zeolites

East European Journal of Physics, 2023
In the course of the research, the effect of competing ions (Na+) on multisorption (Cs+, Sr2+) by composite sorbents based on natural and synthetic zeolites under static conditions was studied.
