, 2008 Gamma rays are a form of high energy emitted from the nucleus of an atom when the nucleus releases energy to move to a state of lower energy. Although damaging to living tissue, gamma rays can also be used beneficially in medicine for both treatment and ...

AIP Conference Proceedings, 1983
The time histories, size spectrum, spatial distribution, and repetition rates of gamma ray bursts are reviewed briefly. Evidence for a neutron star origin for gamma ray bursts may be found in many of these aspects of bursters. New results from optical searches are described.

We summarize the observed features of γ-ray bursts, with particular emphasis on the cyclotron lines seen in their spectra. We then discuss the theory of cyclotron resonant scattering, and compare the theoretical and observed line spectra. Finally, we mention some implications.

Physics Bulletin, 1978
Abstract The potential value of investigation of the γ-ray content of cosmic radiation has long been recognized, but evaluation of measurements made with high-flying balloons is difficult because of the generation of secondary γ-rays in the atmosphere above the detector.

OBSERVATIONS OF THE HIGHEST ENERGY GAMMA-RAYS FROM GAMMA-RAY BURSTS
The Ninth Marcel Grossmann Meeting, 2001EGRET has extended the highest energy observations of gamma-ray bursts to GeV gamma rays. Such high energies imply the fireball that is radiating the gamma-rays has a bulk Lorentz factor of several hundred. However, EGRET only detected a few gamma-ray bursts. GLAST will likely detect several hundred bursts and may extend the maximum energy to a few 100

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1988
Abstract The observational status of gamma-ray astronomy in the TeV energy range is rapidly changing and is reviewed (1987) with emphasis on the limitations of the present observations. It is apparent that gamma-ray detection techniques must be improved and some methods by which this can be achieved are outlined.
