Natural GeF4 is used in the semiconductor pre-amorphisation implant process. The use of Ge-72, in the form of GeF4, improves this process and reduces contamination. Ge-70, Ge-72 and Ge-74 can all be used for the production of the medical radioisotope Se-73, although the most common production route is via natural As (As-75). Natural GeF4 is used in the semiconductor pre-amorphisation implant process. The use of Ge-72, in the form of GeF4, improves this process and reduces contamination. Results show that the Ge content ranges from 60 ppm to 141.5 ppm, and δ74/70Ge values vary from −6.57‰ to 0.97‰.

Structure of odd Ge isotopes with 40 < N < 50. Full Record; Other Related Research The sufficient aspects of model leading to the E(5) symmetry have been proved by presenting E(5) characteristic of the transitional nuclei 64-80Ge. The positive parity states of even-mass Ge nuclei within the framework of Interacting Boson Model have been calculated and compared with the Davidson potential predictions along with the experimental data. We present measurements of Ge isotope composition and ancillary data for samples of river water, low- and high-temperature hydrothermal fluids, and seawater. The dissolved δ74Ge composition of analyzed rivers ranges from 2.0 to 5.6 per mil, which is significantly heavier than previously determined values for silicate rocks (δ74Ge=0.4-0.7 per mil, Escoube et al., Geostand. The removal of chemical species from seawater during the precipitation of authigenic minerals is difficult to constrain but may play a major role in the global biogeochemical cycles of some elements, including silicon (Si) and germanium (Ge).

Both theoretical calculations and adsorption and coprecipitation experiments indicate that light Ge isotopes are preferentially enriched on the surfaces of Fe-oxyhydroxides (Δ 74 Ge Fe-oxide–Solution = − 1.6 to −4.4‰) (Li and Liu, 2010, Pokrovsky et al., 2014). Filtered river water (0.5 to 1.0 L) containing 6–18 ng of Ge was acidified with distilled HNO 3 and spiked with a Ge isotope double spike (73 Ge/ 70Ge ≈ 1, previously calibrated and used by Escoube et al., 2012, 2015 and Baronas et al., 2018, 2019). There are five naturally occurring stable Ge isotopes, 70 Ge (relative isotopic abundance of 20.8%), 72 Ge (27.5%), 73 Ge (7.73%), 74 Ge (36.28%) and 76 Ge (7.61%), whereas at least 27 synthetic radioisotopes have been artificially produced from 58 Ge to 89 Ge with half-lives from 110 ηs to 270.95 d (Audi et al., 2003). Isotopes: There are 30 known isotopes of germanium ranging from Ge-60 to Ge-89. There are five stable isotopes: Ge-70 (20.37% abundance), Ge-72 (27.31% abundance), Ge-73 (7.76% abundance), Ge-74 (36.73% abundance) and Ge-76 (7.83% abundance).

Isotoper är varianter av atomer med olika antal neutroner av ett och samma grundämne. De har därmed samma antal protoner men olika masstal. Atomslaget bestäms av antalet protoner i kärnan, atomnumret, och är avgörande för elektronkonfigurationen, och därmed de kemiska egenskaperna hos ett ämne. I kärnan finns också för de flesta grundämnen neutroner, som påverkar de kemiska egenskaperna i långt mindre grad. Olika isotoper av samma ämne har därför vanligen Germanium isotopes are mainly used for the production of medical As and Se radioisotopes. Ge-74 is used for the production of As-74, Ge-76 for the production of As-77, Ge-74 for the production of As-73 and Ge-72 for As-72.

Atomic Radius (pm): 137; Atomic Volume (cc/mol): 13.6; Covalent Radius (pm): 122; Ionic Radius: 53 (+4e A shell model study of the low energy region of the spectra in Ge isotopes for 38 ≤N≤50 is presented, analyzing the excitation energies, quadrupole moments, B(E2) values and occupation num b ers. Results show that the Ge content ranges from 60 ppm to 141.5 ppm, and δ74/70Ge values vary from −6.57‰ to 0.97‰. In this respect, −6.57‰ is the most negative Ge isotope composition value reported in any sphalerite or seafloor sulfides to date.

2019-05-15 · The generally lighter or similar Ge isotope compositions of the solid weathering product (soil: average δ 74 Ge = 0.19‰; saprolite: average δ 74 Ge = 0.40‰) and heavier composition of basalt-draining rivers from Hawaii (δ 74 Ge = 2.33–3.63‰, Baronas et al., 2017a), relative to those of basalt (δ 74 Ge = 0.54‰), indicate that light Ge isotopes are preferentially retained and enriched in the solid weathering products.
