Thermoacoustic enrichment of the isotopes of neon
The enrichment of the neon isotopes in a thermoacoustic device is demonstrated. Because the thermal diffusion ratio of neon is small, an apparatus longer than a wavelength was necessary in order to easily observe the separation. The device was modular and extensible, so that arbitrarily large separations could in principle be obtained. The acoustic duct was a series of multiple, identical quart...

متن کاملQuadrupole collectivity in silicon isotopes approaching neutron number N = 28
Quadrupole deformation parameters, |β2,(p,p′)|, have been deduced for 36,38,40Si from measured inelastic proton-scattering cross sections. Due to the strong Z = 14 subshell gap, low-lying quadrupole collectivity in these nuclei is attributed to the excitation of valence neutrons. Enhanced collectivity at N = 26 indicates a reduced N = 28 shell gap at large neutron excess in this chain of isotop...
متن کاملStable isotopes measurements reveal dual carbon pools contributing to organic matter enrichment in marine aerosol
Stable carbon isotope ratios in marine aerosol collected over the Southern Indian Ocean revealed δ13C values ranging from -20.0‰ to -28.2‰. The isotope ratios exhibited a strong correlation with the fractional organic matter (OM) enrichment in sea spray aerosol. The base-level isotope ratio of -20.0‰ is characteristic of an aged Dissolved Organic Matter (DOM) pool contributing a relatively homo...
متن کاملSilica coatings on young Hawaiian basalts: Constraints on formation mechanism from silicon isotopes
Young basalts from Kilauea, on the big island of Hawai’i, frequently feature visually striking, white, orange and blue coatings, consisting of a 10-50 μm layer of amorphous silica, capped, in some cases, by a ~1 μm layer of Fe-Ti oxide [1]. The coatings provide an opportunity to study the early onset of acid-sulfate weathering, a process common to many volcanic environments. Silicon isotopes fr...
