Webstudies of a beam of (nuclear spin ½) silver atoms. Bosons: PAB = + Fermions: PAB = - , Where PAB is the permutation operator and is the wave function, which is the product of an electronic, a vibrational, a rotational, and a nuclear spin wave function: elect vib rot spin. Webof spin species is, the lower the energy per atom. In addition, clusters with the same number of species but in which we kept the 173Yb atoms spin-polarized are more stable than the ones with spin-polarized 171Yb’s. This is due to the weak attraction between 171Yb-171Yb pairs that kicks in when the Pauli restrictions are relaxed.
WebSpin magnetic moment. In physics, mainly quantum mechanics and particle physics, a spin magnetic moment is the magnetic moment caused by the spin of elementary particles. For example, the electron is an elementary spin-1/2 fermion. Quantum electrodynamics gives the most accurate prediction of the anomalous magnetic moment of the electron .
