Isotope shift of a series of Sr isotopes

Zeitschrift für Physik D Atoms, Molecules and Clusters, 1986
We give data of the isotope shift for the strontium isotopes from A=80 to A=90. They are found to be inconsistent with data from another optical transition. Possible reasons for the discrepancy are discussed.

Ca and Sr isotope compositions of rainwater from Guiyang city, Southwest China: Implication for the sources of atmospheric aerosols and their seasonal variations

Atmospheric Environment, 2019
Rainwater samples collected from Guiyang city in southwestern China between May 2009 and December 2010 were analyzed to measure their calcium and strontium isotope compositions.

Sr isotope and major ion compositional evidence for formation of Qarhan Salt Lake, western China

Chemical Geology, 2018
Qarhan Salt Lake (QSL) is the largest potash brine deposit in the continental Qaidam Basin (QB) of western China. The origins of the Qarhan brines, whether from migration of Qaidam mega-paleolakes, paleoriver capture, or mixing of modern river water and ...

Nuclear structure of Sr, Zr, and Mo isotopes

Physical Review C, 1985
The nuclear structure calculations for strontium, zirconium, and molybdenum isotopes are performed in a large configuration space by employing a quadrupole-plus-pairing-interaction Hamiltonian. The possible factors responsible for the sudden onset of deformation at N = 60 in these nuclei are pointed out from the systematics of the occupancies of the ...

Sr isotopic constraints on the process of glauconitization

Geology, 1992
Sr isotopic data of Holocene glauconitic pellets suggest a twofold glauconitization process that is strongly linked to the detrital clay minerals from surrounding mud which act as precursors until the K2O content of the glauconitic material reaches 4%. Above that, a detectable sea-water influence becomes progressively predominant.

Applications of Sr Isotopes in Archaeology

2011
The inclusion of radiogenic strontium isotope (87Sr/86Sr) analysis in archaeological and bioarchaeological research has resulted in the creation of new data by which to evaluate models of migration, culture change, colonization, trade, and exchange. Overwhelmingly, archaeologists have used radiogenic strontium isotope signatures in human enamel and ...

Proton transfer reactions on Sr isotopes

Physical Review C, 1976
We have investigated the proton transfer reactions $^{86}\mathrm{Sr}(d,n)^{87}\mathrm{Y}$, $^{87}\mathrm{Sr}(d,n)^{88}\mathrm{Y}$, and $^{88}\mathrm{Sr}(d,n)^{89}\mathrm{Y}$ at 12 MeV incident deuteron energy. Spectroscopic factors are extracted from a distorted wave Born approximation analysis and compared to the spectroscopic factors extracted from ...

Study of the shape transition in Sr isotopes

Il Nuovo Cimento A, 1987
Shape transitions in Sr isotopes are studied in the conventional shell model. The single-neutron energies are varied linearly in the isotope string to absorb the n-p interactions. It is found that the gross features of the energy spectra and the onset of deformation of98Sr and100Sr can be reproduced.

Mg, Sr and Sr isotope geochemistry of a Belgian Holocene speleothem: implications for paleoclimate reconstructions

Chemical Geology, 2000
In this study, variations in Mg/Ca, Sr/Ca and 87Sr/86Sr ratios in a Holocene Belgian speleothem (cave secondary carbonate deposit) are interpreted in terms of changes in water residence time and changes in weathering processes, possibly induced by changes in West European climate. A stalagmite from the Pere Noel cave (Belgium) was dated with the TIMS U/

Proton capture cross section of Sr isotopes

Nuclear Physics A, 2001
The (p,gamma) cross section of Sr-84,Sr-86,Sr-87 isotopes has been measured using activation technique in the proton energy range between 1.5 and 3 MeV. These reactions are relevant to the p-process of stellar nucleosynthesis and in addition, the reaction cross sections in the mass region up to 100 are also important concerning the rp-process ...
