The relationship between photons, electrons and positrons is discussed. A mechanism of the production of coherent light by lasers is also proposed. The nature of light is intimately concerned with the Special Case of the Theory of Relativity. However the model proposed provides no clue to explain...
Variables used by the Matlab script and their relationship to the final board layout. To simplify these calculations, I wrote aMatlab script. When executed, the Matlab script sets a bunch of variables that control the spacing and position of the LEDs on the bar graph board, calculates the pos...
These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light)...
In summary: So, I would say that while EM waves and photons may have different origins (electrons vs. nuclei), they are ultimately the same thing, just with different properties. Feb 14, 2009 #1 mysearch Gold Member 526 0 I am trying to review some basic physics, purely for my own...
and no matter what its velocity is relative to the object. The invariant mass of a particle is defined as the total energy of the particle measured in the particle’s rest frame divided by the speed of light squared. More generally, the invariant mass is defined via the general relationship...
The photon beams would normally be incident on the target, and the energy range is between 250 keV to several MeV at various angles of the reflected beam. The relationship between the reflection coefficient (RC) and the thickness of the lead covering the ordinary concrete has been studied. ...
In this work we report a case study of the ESR response of watch glasses exposed to 6 MV photons and to 10 MeV electrons. The choice of watch glasses is justified by the fact that watch glasses are very close to the exposed individual. For both types of radiation beams, the absorbed do...

Diamond nanocrystals, or nanodiamonds, are produced from diamond materials that have a high nitrogen content. These nitrogen-rich diamonds are irradiated with high energy electrons which create negatively charged nitrogen-vacancy centers. The irradiated diamonds are then annealed at high temperatures to en...
including the remaining unneutralized ions and electrons. The slow ions resulting from resonant charge exchange define tracks that are favored for conduction of a high current heating pulse in the second stage of device operation, as described below. Additional details and embodiments of the astron ...
