classical electron radius การใช้

• :: The OP is referrring to the classical electron radius.
• 2.8179 ?10 & minus; 15 m is the classical electron radius.
• Where a _ 0 is the Bohr radius and r _ 0 is the classical electron radius.
• Where is the atomic number, the length of the wave vector, and the classical electron radius.
• :: : : : Classical electron radius is a useful characteristic length for the extent of the electric field around an electron.
• The Electron article also tells you the mass and has some discussion of the size ( in terms of the " classical electron radius " ).
• Where e is the charge, uniformly distributed on the surface of a sphere, and a is the classical electron radius, which must be nonzero to avoid infinite energy accumulation.
• In the case of the spherical membrane, classical equations of motion imply that the balance is met for the radius 0.75 r _ e where r _ e is the Classical electron radius.
• This is consistent with the expected value of exactly zero . ( This should not be confused with the classical electron radius, which, despite the name, is unrelated to the actual size of an electron .)
• The current limit is that an electron has no internal structure larger than 10-18 m, consistent with zero size and already 1000 times smaller than the classical electron radius . talk ) 00 : 15, 3 December 2011 ( UTC)
• Where \ alpha is the fine structure constant, r _ e is the classical electron radius, Z is the atomic number of the material and P ( E, Z ) is some complex function that depends on the energy and atomic number.
• :: : : : I think what you're trying to calculate is the classical electron radius, but you must have made a mistake since the answer ( according to the article ) is on the order of 10  " 15 m.
• Incidentally, the value of that makes m _ { \ mathrm { em } } equal to the electron mass is called the classical electron radius, which ( setting q = e and restoring factors of and \ varepsilon _ 0 ) turns out to be
• :: : From our article Classical electron radius : " In fact, modern particle physics experiments indicate that the electron is a point particle, i . e . it has no size and its radius is zero . " You can't get much smaller than that.
• Theoretical and experimental studies have shown that the spin possessed by elementary particles cannot be explained by postulating that they are made up of even smaller particles rotating about a common center of mass analogous to a classical electron radius; as far as can be determined at present, these elementary particles have no inner structure.
• Thus for example whereas the Planck length is the mean square root of the reduced Compton wavelength and half the gravitational radius of any mass, the Stoney length is the mean square root of the'electromagnetic radius'( see Classical electron radius ) and half the gravitational radius of any mass, " m ":
• Where \ lambda is the wavelength of the incoming wave, r _ e is the classical electron radius, L is the thickness of the " screen, " or the length scale over which the majority of the scattering takes place, a is the typical size scale of density irregularities, and \ delta N ^ 2 is the root mean squared variation of the electron density about the mean density.
