RHESSI results on γ-ray lines from diffuse radioactivity
Abstract
Although designed to study solar flares, the Reuven Ramaty High Energy Solar Spectroscopic Imager ( RHESSI), a NASA satellite, has proven to be sensitive to γ-ray lines generated by recently created radionuclei in the inner Galaxy. I present the current state of this investigation, including flux and line shape measurements of the 1809 keV line from 26Al and a preliminary detection of the lines of 60Fe.
