The individual isotopes of neon in energetic solar flare particles have been clearly resolved with a rms mass resolution of 0.20 amu. We find /sup 20/Ne//sup 22/Ne=7.6 (+2.0, -1.8) and /sup 21/Ne//sup 22/Ne< or approx. =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.
