Paper Abstract

The spectrometer SPI - one of the two main instruments aboard ESA's INTEGRAL - is dedicated to high resolution gamma-ray line spectroscopy with modest imaging. SPI will mainly concentrate on the study of lines from radioactive isotopes. A wealth of new information is expected from interstellar line emission with narrow line profiles. But existing results are also expected from profile measurements of individual line emitting objects such as supernovae, supernova remnants, novae or stellar black hole systems. In addition, sensitive measurements of continuum emission from compact sources and from interstellar space are expected, especially in the sub-MeV region.
