Photon Energy

Some articles on energy, photon, photons, photon energy:

Transduction (biophysics)
... Photonic energy, the kinetic energy of a photon, may follow the following paths be released again as a photon of less energy be transferred to a recipient with no ... The resulting NADP in turn will use the stored energy in the generation of ATP, which is the end point of the light-induced photosynthetic process ... This means that the photon's energy ends up its circuit by being transduced to an electron that takes part in the formation of a molecular link of energy-rich phosphate ...
Inverse Photoemission Spectroscopy
... beam of electrons of a well defined energy (< 20 eV) is directed at the sample ... The photons emitted in the decay process are detected and an energy spectrum, photon counts vs ... incident electron energy, is generated ...
Laser-based Angle-resolved Photoemission Spectroscopy - Laser-based ARPES - Background
... most importantly, provides the unprecedented higher bulk sensitivity due to the low photon energy, typically 6 eV, and consequently the longer photoelectron mean free path (2–7 nm) in ... significant the photoelectrons will be more broadly dispersed in emission angle when the energy of incident photon decreases ... of the electron spectrometer, the lower photon energy leads to higher momentum resolution ...
Gamma Ray - Properties - Matter Interaction
... Photoelectric effect This describes the case in which a gamma photon interacts with and transfers its energy to an atomic electron, causing the ejection of ... The kinetic energy of the resulting photoelectron is equal to the energy of the incident gamma photon minus the energy that originally bound the ... The photoelectric effect is the dominant energy transfer mechanism for X-ray and gamma ray photons with energies below 50 keV (thousand electron volts), but it is much ...
Laser-based Angle-resolved Photoemission Spectroscopy
... is shone by light, the electrons can absorb photons and escape from the material with the kinetic energy, where is the incident photon energy, the work function of the material ... Since the kinetic energy of ejected electrons are highly associated with the internal electronic structure, by analyzing the photoelectron spectroscopy ... (ARPES) is widely used to provide the dispersive energy-momentum spectrum ...

Famous quotes containing the word energy:

    Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.
    George F. Will (b. 1941)
