Аннотация:The COMPTEL telescope on board the Compton Gamma-Ray Observatory (CGRO) is capable of imaging gamma-ray line sources in the MeV region at a sensitivity of the order of 10-5photons/(cm2s). During two observation periods in July 1992 and February 1993 the Galactic plane in the region of the young supernova remnant Cas A was observed. Imaging and spectral analyses show evidence for line emission of 44Ti at 1.16 MeV from a position of Cas A at a significance level of ~4σ.
