Here we propose a more convincing way of defining the intrinsic magnetic moment of the electron, which does not use any regularizations and is not based on an interaction with external fields. A pseudostatic 1-electron state is defined in a phenomenological way. Its magnetic moment, as defined...
In his theory the angular momentum is still h/4π. The magnetic moment , however, is only approximately the Bohr magneton . Using Darwin'sexplicit expressions for the four ψ's, the magnetic moment of the electron in the field of a charge Ze is easily calculated. The result is where a...
We have evaluated all 891 Feynman diagrams which contribute to the eighth order term in the perturbation expansion of quantum electrodynamics (QED) of the magnetic moment of the electron. Our preliminary result is -0.8 (2.5) ((alpha)/(pi))('4). The theoretical error represents the estimated ...
The magnetic moment of the bound electron is significantly different from that of the free electron. This is true for any binding situation, but particularly pronounced when the electron is bound in a highly charged ion, where it is subject to extreme electromagnetic fields in the close vicinity...

A magnetic moment refers to the magnetic properties of a material, which are caused by the motion of electrons in atoms. The motion can be either spin or orbital, and it results in a magnetic moment associated with the electron. The magnetic moment is expressed in terms of the Bohr magneton...

摘要: The gauge-invariant contribution to the anomalous magnetic moment of the electron (or muon) from four diagrams has been calculated. The results is infra-red convergent and numerically equal to: ( απ) 3{0.477±0.023}.关键词: n34220* --physics (high energy)--particle interactions & ...
(Phys.org)—An electron, as well as other subatomic particles with an electric charge, is actually a little magnet—it spins like a top, giving it its own magnetic moment.
