A novel design for a compact gamma-ray spectrometer is presented. The proposed system allows for spectroscopy of high-flux multi-MeV gamma-ray beams with MeV energy resolution in a compact design. In its basic configuration, the spectrometer exploits conversion of gamma-rays into electrons via Compton scattering in a low-Z material. The scattered electron population is then spectrally resolved ...

diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (om), microhardness depth profiling (hdp), scanning electron microscopy (sem), x-ray diffraction (xrd), glow discharge optical emission spectroscopy (gdoes), and secondary ion mass spectroscopy (sims). plasma nitri...

We present an analysis of time-resolved optical emissions observed from the gamma-ray burst GRB 081126 during the prompt phase. The analysis employed time resolved photometry using optical data obtained by the TAROT telescope, using BAT data from the Swift spacecraft and time resolved spectroscopy at high energies from the GBM instrument onboard the Fermi spacecraft. The optical emission of GRB...

The Mössbauer effect was first described by Rudolf Mössbauer in 1957. The effect describes how nuclei can emit or absorb gamma-rays without recoiling under certain circumstances. When a free nuclei emits or absorbs gamma-rays, it recoils as a result of energy and momentum conservation. As a result, if a free nucleus undergoes a transition from an excited state to its ground state by emitting ga...

A detailed investigation on the relative isotopic distributions has been carried out for first time in case of even-even correlated fission fragments $^{235}\mathrm{U}({n}_{\text{th}},f$) reaction. High-statistics data were obtained a prompt $\ensuremath{\gamma}$-ray spectroscopy measurement during EXILL campaign at ILL, Grenoble, France. The extensive off-line analysis coincidence have using f...

 To the best of our knowledge, imaging of accidental exposure to radioactive fluorine-18 (F-18) due to liquid spill has not been described earlier in the scientific literature. The short half-life of F-18 (t½=110 min), current radiation safety requirements, and Good Manufacturing Practice (GMP) regulations on radiopharmaceuticals have restrained the occurrence of these incidents. The possibilit...
