The early 1970s saw a new and surprising feature in the composition of solar energetic particles (SEPs), resonant enhancements up to 10,000-fold in the ratio 3He/4He that could even make 3He dominant over H in rare events. It was soon learned that these events also had enhancements in the abundances of heavier elements, such as a factor of ∼10 enhancements in Fe/O, which was later seen to be part of a smooth increase in enhancements vs. mass-to-charge ratio A/Q from H to Pb, rising by a factor…

Abstract3He-rich solar energetic particle (SEP) events show huge enrichments of 3He and association with kilovolt electrons and Type-III radio bursts. Observations from a new generation of high
Evidence for a Common Acceleration Mechanism for Enrichments of He-3 And Heavy Ions in Impulsive SEP Events
We have surveyed the period 1997–2015 for a rare type of 3He-rich solar energetic particle (SEP) event, with enormously enhanced values of the S/O ratio, that differs from the majority of 3He-rich

TLDR
3He and Fe remnants from impulsive events present on a majority of the days, implying that they fill a substantial volume of the in-ecliptic interplanetary medium during the authors' survey, and it is suggested that these suprathermal ions may be a source population that is available for further acceleration by Interplanetary shocks, thereby leading to the 3He enhancements in a significant fraction of large SEP events.
Abundances of Heavy and Ultra-Heavy Ions in 3He-Rich Solar Flares
We have surveyed 3He-rich solar energetic particle (SEP) events over the period 1997 September-2003 April in order to characterize abundances of heavy ions near 400 keV nucleon-1. The first part of
Association of 3He-Rich Solar Energetic Particles with Large-Scale Coronal Waves
Small 3He-rich solar energetic particle (SEP) events have been commonly associated with extreme-ultraviolet (EUV) jets and narrow coronal mass ejections (CMEs) which are believed to be the signatures
The Two Sources of Solar Energetic Particles
Evidence for two different physical mechanisms for acceleration of solar energetic particles (SEPs) arose 50 years ago with radio observations of type III bursts, produced by outward streaming
3He-Rich Solar Energetic Particles in Helical Jets on the Sun
Particle acceleration in stellar flares is ubiquitous in the Universe, however, our Sun is the only astrophysical object where energetic particles and their source flares can both be observed. The
Sixty Years of Element Abundance Measurements in Solar Energetic Particles
Sixty years ago the first observation was published showing solar energetic particles (SEPs) with a sampling of chemical elements with atomic numbers $6 \leq Z \leq 18$ 6 ≤ Z ≤ 18 above 40 MeV
3He-Rich Solar Energetic Particles: Solar Sources
3He-rich solar energetic particles (SEPs), showing up to a 10,000-fold abundance enhancement of rare elements like 3He or ultra-heavy nuclei, have been a puzzle for more than 50 years. One reason for
