High-resolution gamma ray spectroscopy measurements of the fast ion energy distribution in JET 4He plasmas

High-resolution γ -ray measurements were carried out on the Joint European Torus (JET) in an experiment aimed at accelerating 4He ions in the MeV range by coupling third harmonic radio frequency heating to an injected 4He beam. For the first time, Doppler broadening of γ -ray peaks from the 12C(d, pγ )13C and 9Be(α, nγ )12C reactions was observed and interpreted with dedicated Monte Carlo codes...

Simulation of Neutron and Gamma Ray Emission from Fission

High Resolution Calculations of Merging Neutron Stars III: Gamma-Ray Bursts

Recent three dimensional, high-resolution simulations of neutron star coalescences are analysed to assess whether short gamma-ray bursts (GRBs) could originate from such encounters. The two most popular modes of energy extraction – namely the annihilation of νν̄ and magnetohydrodynamic processesare explored in order to investigate their viability in launching GRBs. We find that νν̄ annihilation c...

High-resolution X-ray emission and X-ray absorption spectroscopy.

In this review, high-resolution X-ray emission and X-ray absorption spectroscopy will be discussed. The focus is on the 3d transition-metal systems. To understand high-resolution X-ray emission and resonant X-ray emission, it is first necessary to spend some time discussing the X-ray absorption process. Section II discusses 1s X-ray absorption, i.e., the K edges, and section III deals with 2p X...
