The Dirac equation predicts the muon gyromagnetic ratio g=2. Loop effects from quantum field theory lead to a small deviation from this value, parameterized by the so called anomalous magnetic moment which is defined as aμ=(g-2)/2. The difference…

Nuclear quadrupole moments (Q), a measure of charge asymmetry in nuclei, are experimentally accessible via the quadrupole interaction frequency νQ=eQVzz/h. To extract Q from this information one needs to know Vzz, the electric-field gradient at the…
