ISEE 3 Isotopic Fractions

ReleaseDate

Description

This data product consists of a single ASCII file
containing values and their uncertainties for isotopic fractions of 56
specific isotopes relative to isotope-integrated elemental abundances,
for 15 elements (Be, B, N, S, Cl, Ar, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni).
Between this data product and a companion product with isotopic abundance
ratios, isotopic composition information is given for 21 chemical elements.
The fractions are based on 1978-1981 observations of ~50-500 MeV/n cosmic
rays by the U. Chicago cosmic ray experiment on ISEE 3. Each of the ratios
is linked in the ASCII file to the publication where its derivation is
discussed.
