Early SPI/INTEGRAL measurements of 511 keV line emission from the 4th quadrant of the Galaxy
Astronomy & Astrophysics, 2003•aanda.org
We report the first measurements of the 511 keV line emission from the Galactic Centre (GC)
region performed with the spectrometer SPI on the space observatory INTEGRAL
(International Gamma-Ray Astrophysics Laboratory). Taking into account the range of
spatial distribution models which are consistent with the data, we derive a flux of ph cm-2 s-1
and an intrinsic line width of keV (FWHM). The results are consistent with other high-
spectroscopy measurements, though the width is found to be at the upper bound of …
