: an integer that expresses the component of the quantized angular momentum of an electron, atom, or molecule in the direction of an externally applied magnetic field Word History First Known Use 1923, in the meaning defined above Time Traveler The first known use of magnetic quantum number ...
The distributions are found to depend significantly on both the ℓ and mℓquantum numbers of the scattered electron. We consider the simple metals Ir and Al. Although the intensity patterns depend strongly on the ℓ quantum number at relatively low energy, even at high energies (around ...
The magnetic dipole moment of an electron can be written in terms of the vector relation between the magnetic moment m¯ and the spin angular momentum S¯ as [37] (8.1)m¯=−γS¯, where γ is the gyromagnetic ratio (γ = m/s). Note that the negative sign in Eq. (8.1) ...
The semiclassical way of incorporating fields in a quantum mechanical framework for electrons is to apply the substitution (45)pˆ→pˆ+eA for the electron momentum operator in the Hamiltonian. Since the DE is linear in the momentum, the four-component relativistic one-electron Hamiltonian with...

(1). It is worth noting that, under such consideration the momentum operator of the charged particle has to be modified. To this end, we minimally couple a four-vector to the momentum operator as follows: ℏp→=(iℏ∇→+ecA→). (3) To indicate the magnetic field and AB flux ...
angular momentum of the pentaquark will be J = 1 2 or J = 3 2 . The magnetic moments of J P = 1 2 + have been calculated in Ref [24]. Now we shall extend the same formalism and discuss the case of J = 3 2 . The flavor wave functions are the same as those given in ...

Stoner replaced the local “free atom-like” energy levels in the Weiss model, which are characterized by their respective magnetic quantum number, by the electronic bandstructure. Due to the crystal field interaction in solids the angular momentum appears to be quenched (angular quantum numbers ...
