Lithium isotopic
WebLithium isotopes have been measured in various modern planktic species and provide values that are generally close to the seawater composition, with a small and relatively consistent offset of ~1‰ towards lower δ 7 Li values [ 7, 25, 26, 27, 28] that differs from the larger fractionation seen in inorganic calcite [ 29, 30, 31, 32, 33 ]. WebAB - Relativistic mean-field calculations have been carried out for Li isotopes using the non-linear Lagrangian parameter set NL2. Both spherically symmetric and axially deformed cases are considered. The binding energies, charge, neutron and matter rms radii, one and two neutron separation energies have been calculated.

Web摘要： [1] We examined the pedogenic behavior of lithium (Li) and its isotopes in Hawaii by sampling same-age lava flows under mean annual rainfall ranging from 18 to 300 cm. Lithium concentrations in these soils vary from 1 to 29 ppm. WebAll lithium atoms have three protons but could have between zero and nine neutrons. There are ten known isotopes of lithium, ranging from Li-3 to Li-12. Many lithium isotopes …
