چکیده

The individual isotopes of neon in energetic solar flare particles have been clearly resolved with arms mass resolution of 0.20 amu. We find 20Ne/22Ne = 7.6 ( +2.0, -1.8) and 21Ne/22Ne < 0.11 in the 11-26 MeV per nucleon interval. This isotopic composition is essentially the same as that of meteoritic planetary neon-A and is significantly different from that of the solar wind.

Isotopic and elemental fractionation of solar wind implanted in the Genesis concentrator target characterized and quantified by noble gases

We report concentrations and isotopic compositions of He, Ne, and Ar measured with high spatial resolution along a radial traverse of a silicon carbide (SiC) quadrant of the Genesis mission concentrator target. The Ne isotopic composition maps instrumental fractionation as a function of radial position in the target: the maximum observed isotopic fractionation is approximately 33& per mass unit...

Sh 5.1-5 Isotope Abundances of Solar Coronal Material Derived from Solar Energetic Particle Measurements

Coronal isotopic abundances for the elements He, C, N, 0, Ne, and Mg are derived from previously published measurements of solar energetic particles by first measuring, and then correcting for the charge-to-mass-dependent fractionation due to solar flare acceleration and propagation processes. The resulting coronal composition generally agrees with that of other samples of solar system material...

Constraints on neon and argon isotopic fractionation in solar wind.

To evaluate the isotopic composition of the solar nebula from which the planets formed, the relation between isotopes measured in the solar wind and on the Sun's surface needs to be known. The Genesis Discovery mission returned independent samples of three types of solar wind produced by different solar processes that provide a check on possible isotopic variations, or fractionation, between th...

Solar Wind Neon in the Genesis Concentrator Gold Cross by Uv Laser Ablation: First Preliminary Data

Introduction: To determine the oxygen isotopic composition of the present day solar wind is one of the key goals of the Genesis solar wind (SW) collection mission, as the solar wind is a proxy for the solar nebula. In order to increase the number of atoms to be analysed and hence analytical precision on O isotopes, SW ions in the mass range up to 28 amu were accelerated and focussed onto a "con...
