Physics of Solar Neutron Production: Questionable Detection of Neutrons from the 2007 December 31 Flare
Gerald H. Share, Ronald J. Murphy, Allan J. Tylka +3
Spacecraft observations in the inner heliosphere offer the first opportunity to measure 1-10 MeV solar neutrons. We discuss the physics of low-energy neutron production in solar fl…
Delayed X- and Gamma-Ray Line Emission from Solar Flare Radioactivity
V. Tatischeff, B. Kozlovsky, J. Kiener +1
We have studied the radioactive line emission expected from solar active regions after large flares, following the production of long-lived radioisotopes by nuclear interactions of…
Issues of LiBeB, Oxygen and Iron Evolution
R. Ramaty, R. E. Lingenfelter, B. Kozlovsky
We discuss the highlights of our recent research, specifically the refractory vs. volatile interpretation of the rise of [O/Fe] with decreasing [Fe/H], and the issue of primary vs.…
LiBeB, O and Fe Evolution: Refractory Element and Cosmic Ray Transport Delays
R. Ramaty, B. Kozlovsky, R. E. Lingenfelter
Employing a Monte-Carlo based evolutionary code, we show that the delay of Fe deposition relative to O, due to the incorporation of supernova ejecta refractories in high velocity g…
Lithium-6 from Solar Flares
R. Ramaty, V. Tatischeff, J. P. Thibaud +2
By introducing a hitherto ignored Li-6 producing process, due to accelerated He-3 reactions with He-4, we show that accelerated particle interactions in solar flares produce much m…
LiBeB Evolution: Three Models
R. Ramaty, R. E. Lingenfelter, B. Kozlovsky
We consider the three principal LiBeB evolutionary models, CRI in which the cosmic-ray source at all epochs of Galactic evolution is the average ISM, CRI+LECR in which metal enrich…
