摘要：

Measurements of the O-16 and O-18 distribution functions in the solar wind at low to average solar wind speeds from the MASS instrument on the wind spacecraft are reported. The O-16/O-18 density ratio is 450 +/- 130, a value consistent with terrestrial, solar photospheric, solar energetic particle, and galactic cosmic ray O-16/O-18 isotopic ratios. This study constitutes the first reported spacecraft measurement of the isotope O in the core solar wind and may represent the best determination of the solar O-16/O-18 density ratio to date.
