Gamma-Ray Line Observations with RHESSI
David M. Smith
Abstract
The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) has been observing gamma-ray lines from the Sun and the Galaxy since its launch in February 2002. Here I summarize the status of RHESSI observations of solar lines (nuclear de-excitation, neutron capture, and positron annihilation), the lines of 26Al and 60Fe from the inner Galaxy, and the search for positron annihilation in novae.
