Q: The magnetic moment of a charged particle is equal to this quantity times the g-factor times charge divided by two times the mass. Delta baryons have a value of 1.5 for this quantity, and, like other particles with half-integer values of this quantity, obey Fermi-Dirac statistics, whereas those with integer values obey (*) Bose-Einstein statistics. The Pauli Exclusion Principle states that pairs of electrons in the same orbital sub-shell must have opposite values of this quantity. For ten points, identify this quantum number, the angular momentum of a sub-atomic particle.
