Oxygen Isotopes and Volatiles in Martian Meteorite [PDF]

, 2013
Oxygen isotopes were measured in mineral separates from martian meteorites using laser fluorination and were found to be remarkably uniform in both δ18O and Δ17O, suggesting that martian magmas did not assimilate aqueously altered crust regardless of any

Extreme shape coexistence observed in 70Co

Communications Physics
The shape of the atomic nucleus is a property that underpins our understanding of nuclear systems, impacts the limits of nuclear existence, and enables probes of physics beyond the Standard Model.

Stable and radiogenic isotopes as tracers for soil degradation [PDF]

, 2008
Soil erosion seriously threatens mountain slopes. Direct measurement of soil erosion in the field is difficult and needs long term recording. However, stable and radiogenic isotopes are potential tracers for soil erosion estimation and would enable a ...
