Summary
| Description |
English: The Oriented Scintillation Spectrometer Experiment (OSSE) consists of four NaI scintillation detectors, sensitive to energies from 50 keV to 10 MeV. Each of these detectors can be individually pointed. This allows observations of a gamma-ray source to be alternated with observations of nearby background regions. An accurate subtraction of background contamination can then be made. |

The OSSE instrument has produced observations of the energy spectrum of nuclear lines in solar flares, the radioactive decay of nuclei in supernova remnants, and the signature of matter-antimatter (electron-positron) annihilation in the Galactic center region.
