  Observations of the central radian of the Galaxy by the Reuven Ramaty High
Energy Solar Spectroscopy Imager (RHESSI) have yielded a high-resolution
measurement of the 1809 keV line from 26Al, detected at 11 sigma significance
in nine months of data. The RHESSI result for the width of the cosmic line is
2.03 (+0.78, -1.21) keV FWHM. The best fit line width of 5.4 keV FWHM reported
by Naya et al. (1996) using the Gamma-Ray Imaging Spectrometer (GRIS) balloon
instrument is rejected with high confidence.
