We have been developing a Compton scatter polarimeter for measuring the linear polarization of hard X-rays (100-300 keV) from astrophysical sources. A laboratory prototype polarimeter has been used to successfully demonstrate the reliability of our M

We present a compilation of data for all 258 gamma-ray —ares detected above 300 keV by the Gamma Ray Spectrometer (GRS) aboard the Solar Maximum Mission satellite. This gamma-ray —are sample was collected during the period from 1980 February to 1

Since its launch in April of 1991, the COMPTEL experiment on the Compton Gamma-Ray Observatory has surveyed the entire sky in the energy range of 0.75–30.0 MeV. Here we survey the latest results obtained from the COMPTEL data with respect to galact

The ability to measure solar flare neutrons by the COMPTEL γ-ray telescope on-board the Compton Gamma Ray Observatory has been demonstrated during the observations of the powerful solar flares of June 1991 from Active Region 6659. We present intensi

We report on the response of a prototype detector to medium energy neutrons. The neutrons were produced by n-p scattering of a neutron beam on a hydrogen target. The measurements provide unique data on the efficiency and response of large NaI scintil
