Dirac quantization

Dirac quantization

[di′rak ‚kwän·tə′zā·shən]
(quantum mechanics)
The condition, arising from conservation of angular momentum, that for any electric charge q and magnetic monopole with magnetic charge m, one has 2 qm = nc, where n is an integer, ℏ is Planck's constant divided by 2π, and c is the speed of light (gaussian units).
