RHESSI Observations of Galactic Nucleosynthesis
Abstract
The Reuven Ramaty High Energy Solar Spectroscopic Imager, while designed to study solar flares, can also intercept photons from any direction in the sky above about 100 keV, since its germanium detectors are unshielded. Using occultation by the Earth, we have observed the Galactic lines of 26Al and 60Fe with RHESSI (the latter at marginal significance). We will report on the status of these ongoing observations and on the sensitivity of RHESSI to the positron-annihilation line from classical novae.
