Limits for an inverse bremsstrahlung origin of the diffuse Galactic soft gamma-ray emission
Martin Pohl
RXTE, GINGA, and OSSE observations have revealed an intense low-energy gamma-ray continuum emission from the Galactic plane, which is commonly interpreted as evidence for the possi…
An annihilation fountain at the Galactic center?
Martin Pohl
Recently, data of taken with the OSSE experiment have been combined with scanning observations by TGRS and SMM to produce maps of the narrow Galactic 511 keV line emission (Purcell…
Diffuse gamma-ray emission: Galactic and extragalactic
Martin Pohl
Here is reviewed our current understanding of Galactic and extragalactic diffuse gamma-ray emission. The spectrum of the extragalactic gamma-ray background above 30 MeV can be well…
Electron acceleration in SNR and diffuse gamma-rays above 1 GeV
Martin Pohl, Joseph A. Esposito
The recently observed X-ray synchrotron emission from four supernova remnants (SNR) has strengthened the evidence that cosmic ray electrons are accelerated in SNR. We show, that if…
Charge Determination of High Energy Electrons and Nuclei by Synchrotron Radiation with AMS
H. Hofer, M. Pohl
We investigate the possibilities to identify the charge of TeV electrons and PeV nuclei using their synchrotron radiation in the earth's magnetic field. Characteristics of synchrot…
The HERMES Back Drift Chambers
S. Bernreuther et al
The tracking system of the HERMES spectrometer behind the bending magnet consists of two pairs of large planar 6-plane drift chambers. The design and performance of these chambers…
