26Al in the inner Galaxy
R. Diehl, H. Halloin, K. Kretschmer +12
We performed a spectroscopic study of the 1809 keV gamma-ray line from 26Al decay in the Galaxy using the SPI imaging spectrometer with its high-resolution Ge detector camera on th…
Properties of the energetic particle distributions during the October 28, 2003 solar flare from INTEGRAL/SPI observations
J. Kiener, M. Gros, V. Tatischeff +1
Analysis of spectra obtained with the gamma-ray spectrometer SPI onboard INTEGRAL of the GOES X17-class flare on October 28, 2003 is presented. In the energy range 600 keV - 8 MeV…
The all-sky distribution of 511 keV electron-positron annihilation emission
J. Knödlseder, P. Jean, V. Lonjou +11
We present a map of 511 keV electron-positron annihilation emission, based on data accumulated with the SPI spectrometer aboard ESA's INTEGRAL gamma-ray observatory, that covers ap…
SPI energy calibration
V. Lonjou, J. Knodlseder, J. P. Roques +7
The status of the SPI energy calibration after the first year of INTEGRAL operations is reported. We have studied the gain variations and we have demonstrated that the most importa…
