quantum number

n.
Any of a set of real numbers assigned to a physical system that individually characterize the properties and collectively specify the state of a particle or of the system.

quantum number

n
(Atomic Physics) physics one of a set of integers or half-integers characterizing the energy states of a particle or system of particles. A function of the number multiplied by a fixed quantity gives the observed value of some specified physical quantity possessed by the system
