Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

X-Ray Spectrometry, EarlyView.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.

Subtracting Interferences in X‐Ray Spectra Obtained With Grating Spectrometers

X-Ray Spectrometry, EarlyView.
ABSTRACT Higher order diffraction from surface contamination poses a major challenge for soft x‐ray spectral analysis using reflection zone plate spectrometers in electron probe microanalysis. We developed two correction methods applied to the Al L2,3 and Zn M2,3 emissions in AlZn60 alloy spectra: sequential overlay and subtraction of C Kα and O Kα ...

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

Acta Crystallographica Section B, EarlyView.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...

Manobra orbital terra-lua-terra

, 2014
In the present work an Earth-Moon-Earth orbital maneuver is studied with the purpose of minimum fuel consumption. Initially it is considered an artificial satellite orbiting around the Earth. In a certain instant an impulse is effected to effect a not cofocal maneuver where the satellite is transferred to an orbit of geocentric transference until a ...
