Ge isotopes

Full Record; Other Related Research The aging reactor is one of six worldwide -- none located in the United States -- to produce molybdenum-99 or MO-99, the most commonly used medical isotope. GE Hitachi said the new technology does The strong variation in energy of the first excited 0+ state in the even-even Ge isotopes is investigated with pairing type interactions in various model spaces. Although it had been possible in previous work to describe this variation in a BCSrandom-phase-approximation (RPA) calculation in the neutron configuration only, the corresponding exact diagonalization disagrees with the BCS-RPA Se hela listan på nuclearpharmacy.uams.edu GE Healthcare and SHINE Medical Technologies have done just that: they tested and verified a new way to manufacture Mo-99. Jan Makela, general manager of core imaging for GE Healthcare, and his team went out to the industry to find another source of Mo-99 that could help break through the bottleneck.

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).

2017-04-15 · Germanium has five naturally occurring isotopes: the stable isotopes are 70 Ge (20.4% abundance), 72 Ge (27.3%), 73 Ge (7.8%), and 74 Ge (36.7%), while 76 Ge (7.8%) is slightly radioactive (half life of 1.55 × 10 21 years) (Klapdor-Kleingrothaus et al., 2001, de Laeter et al., 2000).
