Quasiclassical quantization of the magnetic charge Available to Purchase

Quasiclassical quantization of a spherical pendulum in which the moving point mass and the center have electric and magnetic charge, respectively, is discussed. It is shown that for this system quantum conditions do not simply select between classical orbits. The requirement of spherical symmetry leads to the quantization condition of Dirac for the product of the charges and the total angular momentum may be either an integer or a half‐integer multiple of h/.
