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 quan′tum num`ber n. any integer or half of an odd integer that distinguishes one of the discrete states of a quantum-mechanical system.
quantum number
quantum number One of a set of integers or half integers characterizing the energy states of an elementary particle or system of particles. Physical properties, such as charge and spin, are described by quantum numbers.quantum number[′kwän·təm ‚nəm·bər] (quantum mechanics) One of the quantities, usually discrete with integer or half-integer values, needed to characterize a quantum state of a physical system; they are usually eigenvalues of quantum-mechanical operators or integers sequentially assigned to these eigenvalues. |
