The distinction between X-rays and gamma rays is not so simple and has changed in recent decades. According to the currently valid definition, X-rays are emitted by electrons outside the nucleus, whilegamma rays are emitted by the nucleus. For X-r...
X-rays: burstsGamma-ray bursts (GRBs) can be divided into three groups: short-, intermediate- and long-duration bursts. While the progenitors of the short and long ones are relatively known, the progenitors of the intermediate-duration bursts (IBs) are generally unknown. However, recent ...
Isolation of X-rays and gamma rays by a common alternative wavelength (or equivalent frequency or photon energy). Below any wavelength is defined as noncombustion, such as 10−11 m (0.1 A), called a gamma ray. This parameter allocates photons in an ambiguous range, but it is possible ...
Since the rate of these candidate afterglow events, 0.15 /day, isconsistent with the BATSE logN-logS distribution, no difference in prompt vs.afterglow beaming is required. However more sensitive x-ray monitors or hardx-ray imaging surveys, with better temporal and spatial resolution, couldprovide...

Cadmium zinc telluride CZT is a room temperature semiconductor that directly converts X-ray or gamma-ray photons into electrons. Kromek specialises in growing CZT crystals and turning it into radiation detectors that offer excellent energy resolution and
Gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. It includes some overlap with X-rays in the el
Gamma-ray telescope, instrument designed to detect and resolve gamma rays from sources outside Earth’s atmosphere. Gamma rays are the shortest waves (about 0.1 angstrom or less) and therefore have the highest energy in the electromagnetic spectrum. Sinc
Gamma rays are a form of electromagnetic radiation. They can be used to treat cancer, and gamma-ray bursts are studied by astronomers.
The meaning of GAMMA RAY is a photon emitted spontaneously by a radioactive substance; also : a photon of higher energy than that of an X-ray.
