Two components in major solar particle events (2003, background): “However, the heavy ion enhancements are not correlated with the (3)He to (4)He ratio [Reames, 1999] and the lower limit to (3)He/(4)He in flare events has not yet been determined.”
Hard X-ray emission from the solar corona (2008, background): “Keywords Sun · Corona · Hard X-rays S. Krucker Space Sciences Laboratory, UC Berkeley Tel.”
Type II radio bursts and energetic solar eruptions (2003, background): “There were 11 events with intensity between 1 and 9 pfu, which are known as minor SEP events [Gopalswamy et al., 2002], but they are much larger than the typical impulsive events [see e.g., Reames, 1999 ].”
The Near-Earth Space Radiation Environment (2008, background): “CMEs tend to be proton rich, last for days, and have a small He content relative to He.”
Differences between CME‐driven storms and CIR‐driven storms (2006, background): “Energetic-particle events are also produced by CIRs (by CIR shocks in the heliosphere beyond 2 AU, with the energetic particles traveling back to 1 AU) [Reames, 1999b], but their intensity at Earth is weak compared with CME-related SEP events [Mason and Sanderson, 1999], extending only to 20 MeV/n.”
Diurnal variation of ozone depletion during the October-November 2003 solar proton events (2005, background): “[2] Solar proton events (SPE) correspond to solar coronal mass ejections (CME) during which a large amount of protons and heavier ions are emitted [ Reames, 1999 ], sometimes toward the Earth.”
Proton, helium, and electron spectra during the large solar particle events of October-November 2003 (2005, background): “3.6. Measurements of the 3 He/ 4 He Ratio [37] Although 3 He is rare on the Sun, it has long been known that impulsive solar flares sometimes show enhancements of 3 He/ 4 He up to 10 4 times the solar value [e.g., Reames, 1999 ].”
Integrated Science Investigation of the Sun (ISIS): Design of the Energetic Particle Investigation (2016, background): “Since CMEs propagate into the ambient corona and the slow solar wind, the associated shocks were generally believed to inject and accelerate coronal or solar wind material (e.g., Reames 1999).”
The Solar Probe Plus Mission: Humanity’s First Visit to Our Star (2016, background): “The acceleration and transport of solar energetic particles (SEPs) has been studied extensively (e.g., Reames 1999; Mewaldt 2006; Lee et al. 2012; Raymond et al. 2012; Drake and Swisdak 2012; Giacalone 2010).”
The Plasma and Suprathermal Ion Composition (PLASTIC) Investigation on the STEREO Observatories (2008, background): “These CIR-related events are known to be an important source of the low-energy interplanetary particle populations during periods of low solar activity (Reames 1999, and references therein).”

A study of solar energetic particle events of 1997–2006: Their composition and associations (2010, background): “These enhanced abundances can be understood in terms of an acceleration process in flares in which particles interact with resonant waves [Reames, 1999].”
