  • What does 100 MeV u mean? How is it different from 100A MeV?
    The value of 1 u is set such that a carbon-12 atom has a mass of exactly 12 u In other words, 1 u is exactly 1 12 of the mass of a carbon-12 atom You may also see this unit being referred to as 1 Dalton, especially in chemistry
  • energy - Why does $^{235}\text U$ fission release about $24 . . .
    Their atomic masses differ by only about 3 u (≈ 0 75%), which naively corresponds to a rest-mass energy difference of roughly 3 u×931 5 MeV u $≈2800\,\text Me\text V$ Yet the fission yield differs by only $≈ 24\,\text Me\text V$
  • Calculating energy release in MeV - Physics Stack Exchange
    If 190 amu is converted into energy for every nucleus of U-235 undergoing fission, then calculate the energy release per nucleon in MeV U-235 has a mass of 235 0439299 Given that it has 143 neutrons and 92 protons, then the following calculation: $$(92\cdot1 007276)+(143\cdot1 008665)-235 0439299=1 864557u$$
  • How to convert MeV to velocity? - Physics Stack Exchange
    Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
  • How to deal with an $\\alpha$ particle in a $^{238}\\,\\,U . . .
    The illustration represents an attempt to model the alpha decay characteristics of polonium-212, which emits an 8 78 MeV alpha particle with a half-life of 0 3 microseconds The Coulomb barrier faced by an alpha particle with this
  • What is exact *average* energy released by uranium fission?
    Quantity Value(MeV) Uncertainty Kinetic energy of the fragments 169 130000 0 490000 Kinetic energy of the prompt neutrons 4 916000 0 070000 Kinetic energy of the delayed neutrons 0 I think the number that is giving you the most problems is the average binding energy of the fission products
  • Energy from 1 gram of fuel in a nuclear power plant?
    The total energy from the fission of one atom of U-235 is 202 5 MeV according to Kaye and Laby Typical nuclear fuel is enriched to about 5% U-235, but never more than about 18% - higher than that and you are talking about material for bombs
  • Binding energies of $Be$ - Physics Stack Exchange
    Just a quick question How does Beryllium 8 decay into 2 alpha particles? Beryllium 8 has a binding energy of 56 499508 Mev An alpha particle has a binding energy of 28 3 so two of these would h
  • What does the $c$ in $eV c^2$ stand for? - Physics Stack . . .
    So one can, for instance, select an energy unit like the mega-electronvolt ($\text{MeV}$) and use this along with a relativistically consistent unit for mass written as $\text{MeV} c^2$ Such an expression denotes nothing more than the amount of mass corresponding with one MeV of rest energy
  • What is mass constituted by quarks in a proton?
    $\begingroup$ 1) Yes, the 30 MeV figure is correct 2) 3-4 pairs is a reasonable number This is what you get if you combine the 37 MeV, with the MS-bar quark masses 2 2 and 4 8 quoted by fermion (I have not checked, but these
