Gamma rays in the energy range above ∼ 30 Gev have not been well sampled from space to date, given their low fluxes, and ground-based techniques have only recently matured to the point where efficient observations are feasible. As outlined previously, cosmic gamma rays are absorbed in the ...
Gamma rays, also called gamma radiation or γ-ray, are a penetrating electromagnetic radiation arising from the radioactive decay of atomic nuclei, which is always obtained from radioisotopes (cobalt-60 or cesium-137) during the application [82]. As with its high energy and strong penetrability,...
"numberOfGammas" A number type (integer) corresponding to the number of deexcitation γ rays belonging to the levels. "gammaDecay" An array type corresponding to the γ-decay properties of the level. "alphaDecay" An array type containing JSON objects associated with the α-decay properties of...
Incoming gamma rays are collimated by a pinhole collimator. The Seracam under test included four different integrated pinhole collimators of nominal diameters 1 mm, 2 mm, 3 mm and 5 mm (actual values measured 1.20 mm, 2.22 mm, 3.07 mm, and 5.00 mm, with a 0.01 mm tolerance), all with...
Imaging of nuclear gamma-ray lines in the 1–10 MeV range is far from being established in both medical and physical applications. In proton therapy, 4.4 MeV gamma rays are emitted from the excited nucleus of either 12C* or 11B* and are considered
Very speculative modeling and discussions are made for considering a nuclear physics possibility of Iwamura-type (A, Z)-selective transmutation without hard gamma-rays. The BOLEP (burst-of-low-energy-photons) energy damping mechanism from very highly excited intermediate nucleus by the 4D/TSC-min ...
(coupling agents) being the most widely known application. However, the composition of these molecules can aid in the creation of a strong contact. Recent research indicates that using polymer nanocomposites can improve interfacial properties8,9. Due to their superficial active chemical sites, nano-...
A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser, which may have appl...
The prompt emission is detected as a bright, impulsive emission of soft Gamma-rays (∼10 keV–10 MeV), with variability of the order of 0.01–1 s, total duration between ∼0.1 s and ∼103103 s, and isotropic equivalent luminosities typically in the range of 𝐿isoLiso∼10501050–...
The second advantage is a fairly good energy resolution in determining energies of excited states. The energies are constructed by γ-ray energies which are measured by the γ-ray detectors installed around the target. A typical energy of γ-rays is of order 1 MeV, and the intrinsic energy ...
