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...
The magnitude of the spin magnetic moment is of the same order of magnitude as the magnetic moment due to orbital motion. The magnitude of the spin angular momentum is given by (15.8)S=ℏ2=5.2729×10−35Js The intrinsic magnetic moment associated with the spin of an electron has the ...
3.1 Magnetic Moment The magnetic properties of a matter are due to the electrons in atoms, which have a magnetic moment by means of electron motion. At the atomic level, there are fundamentally two types of electron motion, spin, and orbital with an associated a magnetic moment with it. The...
Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons. A material’s response to an applied magnetic fie...
Due to symmetry of the charge distributions around the center of the dot, the dipole moment of the qubit is approximately zero, potentially reducing its sensitivity to homogenous electric fields and far-field noise, however, this qubit has quadrupole or higher moments that yield strong sensitivity ...
In order to improve the theoretical prediction of the electron anomalous magnetic moment $a_e$ we have carried out a new numerical evaluation of the 389 integrals of Set V, which represent 6,354 Feynman vertex diagrams without lepton loops. During this work, we found that one of the integral...

We present an analytic calculation of electron and tau O(alpha^3) loop effects on the muon anomalous magnetic moment. Computation of such three-loop diagrams with three mass scales is possible using asymptotic and eikonal expansions. An evaluation of a new type of eikonal integrals is presented ...
For the upcoming measurements, it is essential to evaluate the prediction for this contribution with independent methods and to reduce its uncertainties. The most precise, model-independent determinations so far rely on dispersive techniques, combined with measurements of the cross-section of electron–...
The shift in the white line energy position is primarily due to a lower binding energy of the core electrons in Eu2+ through shielding of the nucleus by the additional 4f electron. Generally, the tabulated value of Eu L3 X-ray absorption edge energy position of 6977 eV23 separates the ...
