52Positron emission tomography — (PET) is a nuclear medicine imaging technique which produces a three dimensional image or map of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron emitting radionuclide (tracer), which is… …
53X-ray binary — Artist s impression of an X ray Binary X ray binaries are a class of binary stars that are luminous in X rays. The X rays are produced by matter falling from one component, called the donor (usually a relatively normal star) to the other… …
54Formation evaluation gamma ray — In the field of formation evaluation, gamma ray log records natural radioactivity emission of formation. Measurement of natural emission of gamma rays in oil and gas wells are particularly helpful because shales and sandstones typically have… …
55Field electron emission — It is requested that a diagram or diagrams be included in this article to improve its quality. For more information, refer to discussion on this page and/or the listing at Wikipedia:Requested images. Field emission (FE) (also known as field… …
56Field emission display — A field emission display (FED) is a display technology that incorporates flat panel display technology that uses large area field electron emission sources to provide electrons that strike colored phosphor to produce a color image as a electronic …
57Ultraluminous X-ray source — An ultra luminous X ray source (ULX) is an astronomical source of X rays that is not in the nucleus of a galaxy, and is more luminous than 1039 erg/s (1032 watts), assuming that it radiates isotropically. Typically there is about one ULX per… …
58Gamma ray burst progenitors — are the types of celestial objects that can emit gamma ray bursts (GRBs). GRBs show an extraordinary degree of diversity. They can last anywhere from a fraction of a second to many minutes. Bursts could have a single profile or oscillate wildly… …
59Induced gamma emission — In physics, induced gamma emission (IGE) refers to the process of fluorescent emission of gamma rays from excited nuclei, usually involving a specific nuclear isomer. It is analogous to conventional fluorescence, which is defined to be the… …
60European x-ray free electron laser — The European x ray free electron laser (XFEL) is a planned European project in strong connection with the DESY research center in Hamburg. [cite web |title=XFEL|url=http://xfel.desy.de/ |format= |accessdate=2007 12 20] . A free electron laser… …
