21Cosmic ray — For the film, see Cosmic Ray (film). Cosmic radiation redirects here. For some background types of cosmic radiation, see cosmic background radiation and cosmic background. The energy spectrum for cosmic rays Cosmic rays are energetic charged… …
22X-ray astronomy — X rays start at 0.008 nm and extend across the electromagnetic spectrum to 8 nm, over which the Earth s atmosphere is opaque. X ray astronomy is an observational branch of astronomy which deals with the study of X ray observation and detection… …
23Gamma ray spectrometer — A Gamma Ray Spectrometer, or (GRS), is an instrument for measuring the distribution (or spectrum see figure) of the intensity of gamma radiation versus the energy of each photon. Gamma rays are electromagnetic radiation at the short wavelength,… …
24t-ray — (TEE ray) n. Terahertz ray; electromagnetic radiation produced at terahertz (trillion cycles per second) frequencies that, like an x ray, can penetrate solids, but that also enables the identification of certain molecules and substances. Also: T… …
25X ray — noun 1. electromagnetic radiation of short wavelength produced when high speed electrons strike a solid target (Freq. 6) • Syn: ↑X ray, ↑X radiation, ↑roentgen ray • Hypernyms: ↑electromagnetic radiation, ↑electromagnetic wave, ↑ …

27X-ray photoelectron spectroscopy — [ right|thumb|350px|Basic components of a monochromatic XPS system.] X ray photoelectron spectroscopy (XPS) is a quantitative spectroscopic technique that measures the elemental composition, empirical formula, chemical state and electronic state… …
28Near edge X-ray absorption fine structure — NEXAFS (Near Edge X ray Absorption Fine Structure) is an element specific electron spectroscopic technique which is highly sensitive to bond angles, bond lengths and the presence of adsorbates. It is widely used in surface science and has also… …
29Annihilation radiation — is a term used in Gamma spectroscopy for the gamma radiation produced when a particle and Antiparticle collide. Most commonly, this refers to 511 keV gamma rays produced by a gamma ray undergoing Pair production [Knoll, G: Radiation Detection and …
30Small-angle X-ray scattering — (SAXS) is a small angle scattering (SAS) technique where the elastic scattering of X rays (wavelength 0.1 ... 0.2 nm) by a sample which has inhomogeneities in the nm range, is recorded at very low angles (typically 0.1 10°). This angular range… …
