Shifts of the Al-26 line due to Galactic rotationThe shape of the Al-26 line is evaluated using a Galactic disk rotation curve and assuming various galactic distributions of radioactive aluminum. The line shape depends on galactic longitude, detector opening angle, and the assumed aluminum distribution. For a detector of 20 deg aperture and 2.5 keV resolution, the shift of the line peak can be as large as 0.4 keV. Such a shift could be detected with the proposed nuclear astrophysics explorer.
