Measurements from the MASS instrument on the WIND spacecraft from late Dec. 94 through Aug. 95 are reported for 20Ne, 16O, and 4He. The average 4He/20Ne density ratio is 566¿87 with considerable variability. The average 16O/20Ne density ratio is 8.0¿0.6 and is independent, within experimental uncertainty, of solar wind speed. The 20Ne/4He and 16O/4He temperature ratios at the lowest solar wind speeds are consistent with unity, increasing with increasing speed to values exceeding that expected from mass proportionality. 20Ne, 16O, and 4He distribution functions exhibit high energy tails which are well-fit by a kappa function. ¿ American Geophysical Union 1996
