Extensive measurements of the composition of energetic solar flare particles have revealed the frequent occurrence of solar flares with large enrichments of 3He and heavy ions compared to the composition of the solar atmosphere. The basic characteristics of these events can be summarized as follows:

  1. – 3He/4He-ratios up to more than 1 are observed

  2. – the 3He/4He-ratio increases with energy

  3. – no comparable enhancement of 2H or 3H is found

  4. – there is a strong correlation of 3He and heavy ion enrichment.
