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…
High-Resolution Spectroscopy of Gamma-Ray Lines from the X-Class Solar Flare of 23 July, 2002
David M. Smith, Gerald H. Share, Ronald J. Murphy +3
The Reuven Ramaty High Energy Solar Spectroscopy Imager (RHESSI) has obtained the first high-resolution measurements of nuclear de-excitation lines produced by energetic ions accel…
Directionality of Solar Flare Accelerated Protons and Alpha Particles from Gamma-Ray Line Measurements
G. H. Share, R. J. Murphy, J. Kiener +1
The energies and widths of gamma-ray lines emitted by ambient nuclei excited by flare-accelerated protons and alpha particles provide information on the ions directionality and spe…
Annihilation Radiation in the Galaxy
C. D. Dermer, R. J. Murphy
Observations of annihilation radiation in the Galaxy are briefly reviewed. We summarize astrophysical mechanisms leading to positron production, and recent estimates for production…
