The combination will result in the emission of energy in the form of gamma-radiation, and assuming that momentum is conserved, the amount of radiation will be roughly equal to half the kinetic energy of the neutron plus the mass d efect of the H 2 nucleus (about one million volts, ...
Switch to new thesaurus Noun 1. antiproton - an unstable negatively charged proton; the antiparticle of a proton nucleon - a constituent (proton or neutron) of an atomic nucleus Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc. Translations --...
My question is: I know it is incorrect to say that a neutron is a "Proton plus Electron and Neutrino," but why is it wrong to say this? I'm familiar with the HUP explanation that since the mass of an electron is so small, then it's position is too vague to be co...
If E p < 20 keV, the defects are “electron-like,” N E; otherwise, they are “neutron-like,” N N. The change in reciprocal lifetime per unit fluence (cm−2) is equal to k E N E plus k N N N, where k E (= 5.4 × 10−9 cm2/sec) and k E (= 10−5 cm2/...
Examples include neutron stars and powerful particle accelerators. What is the opposite of a proton ? This question is not likely to be asked as part of school chemistry tests. If you think this question has been asked on your school chemistry exam look carefully ... perhaps you are being ...
This Clinical Policy Bulletin addresses proton beam, neutron beam, and carbon ion radiotherapy. Medical Necessity Proton Beam Therapy Aetna considers proton beam radiotherapy (PBRT) medically necessary for the curative treatment of any of the following tumors: Primary CNS tumors; or Head and neck tu...
The atomic mass of an atom is approximately equal to the number of protons plus the number of electrons, since the mass of electrons is practically negligible. References Purdue University: Bodner Research Web: The Atom and Electromagnetic Radiation ...
This can occur when all parameters are kept constant in time and for low enough injected luminosities so as to avoid supercriticalities. The solution gives the proton and electron distribution functions, as well as the emerging photon, neutrino, and neutron spectra, which are all calculated ...
The standard shorthand, “the proton is made from two up quarks and one down quark”, is really a statement that the proton has two more up quarks than up antiquarks, and one more down quark than down antiquarks. To make the glib shorthand correct you need to add the phrase “plus ...
the effects of three phenomena add up to generate the required spin-to-orbital angular momentum conversion: one, the relativistic movement of quarks; two, the exchange of gluons when quarks interact; and three, a proton’s brief “fluctuation” into a proton or neutron plus a pion (any flipp...
