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. Controls on Ge isotope fractionation during extreme weathering of basalts. 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.

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‰.

We have interpreted recently measured experimental data of Ge, and also for Ge isotopes in terms of state-of-the-art shell-model calculations. Excitation energies, values, quadrupole moments and magnetic moments are compared with experimental data when available. The calculations have been performed with the recently derived interactions, namely with JUN45 and jj44b for space.

Ge isotopes Germanium has five naturally occurring isotopes: the stable isotopes are 70Ge (20.4% abundance), 72Ge (27.3%), 73Ge (7.8%), and 74Ge (36.7%), while 76Ge (7.8%) is slightly radioactive (half life of 1.55×1021years) (Klapdor-Kleingrothaus et al., 2001, de Laeter et al., 2000). Ge isotopes are characterized by a complex nuclear structure. The irregular dependence of the excitation energies of the first excited 0 2 state with the neutron number, N, and anomalies in the population cross sections for two-neutron transfer reactions [2] strongly suggest that two different configurations, based on the ground state and on the 0 2 state, coexist and are admixed.

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 This is "GE - Isotopes" by The Mark on Vimeo, the home for high quality videos and the people who love them.

Naslov Germanium (32 Ge) has five naturally occurring isotopes, 70 Ge, 72 Ge, 73 Ge, 74 Ge, and 76 Ge. Of these, 76 Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 21 years (130 billion times the age of the universe). Germanium Isotopes are mainly used for the production of medical As and Se radioisotopes.
