11Delbruck scattering — Delbrück scattering, the deflection of high energy photons in the Coulomb field of nuclei as a consequence of vacuum polarization has been observed. However, the process of scattering of light by light, has not been observed.[1] In both cases, it …
12Heisenberg's microscope — exists only as a thought experiment, one that was proposed by Werner Heisenberg, criticized by his mentor Niels Bohr, and subsequently served as the nucleus of some commonly held ideas, and misunderstandings, about Quantum Mechanics. Basic ideas… …
13Coincidence circuit — In physics, a coincidence circuit is an electronic device with one output and two (or more) inputs. The output is activated only when signals are received within a time window accepted as at the same time and in parallel at both inputs.… …
14electromagnetic radiation — Physics. radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x rays, and gamma rays. [1950 55] * * * Energy propagated through free space or through a material medium in the form of… …
15Precision tests of QED — Quantum electrodynamics (QED), a relativistic quantum field theory of electrodynamics, is among the most stringently tested theories in physics.Precision tests of QED consist of measurements of the electromagnetic fine structure constant, α, in… …
16Gamma ray — Gamma rays (denoted as gamma;) are a form of electromagnetic radiation or light emission of frequencies produced by sub atomic particle interactions, such as electron positron annihilation or radioactive decay. Gamma rays are generally… …
17Scintillator — Scintillation crystal surrounded by various scintillation detector assemblies …
18Abraham-Lorentz force — In the physics of electromagnetism, the Abraham Lorentz force is the recoil force on an accelerating charged particle caused by the particle emitting electromagnetic radiation. It is also called the radiation reaction force. The formula for the… …
19Ionizing radiation — consists of highly energetic particles or waves that can detach (ionize) at least one electron from an atom or molecule. Ionizing ability depends on the energy of the impinging individual particles or waves, and not on their number. A large flood …
20Magnetic radiation reaction force — In the physics of electromagnetism, one can derive an electric radiation reaction force for an accelerating charged particle caused by the particle emitting electromagnetic radiation. Likewise, a magnetic radiation reaction force can be derived… …
