"Diffuse" gamma rays consist of several components: truly diffuse emission from the interstellar medium, the extragalactic background, whose origin is not firmly established yet, and the contribution from unresolved and faint Galactic point sources. One approach to unravel these components is to study...

摘要: Using a Wilson cloud chamber in a magnetic field of 1000 gauss we have studied the spectrum of recoil electrons produced by the gamma-rays from boron bombarded with deutons, and have found it to consist of components of at least five different energies....
Gamma ray spectrometers are devices that measure the energy of gamma rays emitted by radioactive elements, allowing for the identification of specific elements like potassium, uranium, and thorium based on their energy peaks in the spectrum.
Above approximately 30 MeV in energy, gamma rays interact predominantly via the pair-production process. The traditional method of detecting such photons is through the use of high-voltage spark-chamber grids, interleaved with sheets of a high-density converter material (such as tungsten). In this...
Gamma-ray binaries consist of a compact object, either a neutron star or black hole, orbiting a massive O or B-type star. While there is some debate around how the gamma rays are produced, in two systems, PSR B1259-63 and PSR J2032+4127, the compact object is known to be a pulsar...
Rays feed on a variety of smaller animals; the heavy, rounded teeth of most species are adapted to crushing the shells of snails and clams. Types of Rays The rays, which form the order Batoidea, are divided into seven families. The largest are the mantas, also called devil rays and ...
gamma rays (γ-rays) electromagnetic emissions from radioactive substances; they are similar to and have the same general properties as x-rays but are produced through the disintegration of certain radioactive elements. They consist of high energy photons, have short wavelengths, and have no mass...
The γ-radiation of a simple radionuclide having a unique γ-energy does not produce a sharp spectral line, but a peak, owing to the statistical nature of the interaction of γ-rays with matter. An NaI(Tl) scintillation detector spectrum for 137Cs is shown in Figure 4. The peak at ...
