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

n.
any integer or half of an odd integer that distinguishes one of the discrete states of a quantum-mechanical system.

The Durham/Cardiff collaboration has existed since 2015; we have preliminary results (observation of Rydberg excitons up to principal quantum number n=12), and developed methods for sample preparation and spectroscopy.
The extended phenomenology studies done for this model shows that [N.sup.0.sub.l], l = e, [mu], [tau] can be identified with the right-handed neutrinos [v.sup.0c.sub.l], which belong to the same 3-3-1 representation of the neutrino fields; so, lepton number is not a good quantum number for this particular model and it is not conserved (Chang & Long, 2006).
In 1913, Bohr introduced the Principal Quantum Number to explain the Rydberg Formula for the spectral emission lines of atomic hydrogen.
Nevertheless, there are three types of quantum chaos [13]: quantum chaology that refers to the study of the quantum signatures of classical chaos in the semiclassical or high quantum number regimes; semiquantum chaos, which refers rigorously to chaotic dynamics in semiquantum system; and genuine quantum chaos, which rigorously refers to chaotic behavior in full quantum systems.
In accordance with current standard notation in spectral analysis, here we use exclusively symbols J for rotational quantum number and v for vibrational quantum number, regardless of the symbols employed in the original sources.
In Figure 4 we present results of calculation of six lower energies corresponding to the radial quantum number n = 1 as functions of the magnetic field in nanotubes with the aperture angle tan [alpha] = 0.25 and dimensions [R.sub.b] = 6[a.sup.*.sub.0], [R.sub.t] = 1[a.sup.*.sub.0], H = 20[a.sup.*.sub.0].
The indices a arising from the use of total potential and occurring in the Guseinov [[psi].sup.([alpha])]-ETOs are the frictional quantum number. For the evaluation of multicenter molecular integrals of integer Slater type orbitals (ISTOs) and noninteger Slater type orbitals (NISTOs) appearing in the CHFR approximation, Guseinov derived one-range addition theorems by the use of complete orthonormal sets of Guseinov [[psi].sup.([alpha])]-ETOs [24].
The results obtained in [1-9] data show that in a homogeneous conductive metal conductor structure comprising quantum number n = 1,2,3...
In this notation, M* is the effective mass of the captured charged particle in an orbital state with angular momentum quantum number L.
Here, we assign the vibrational quantum number n to a diatom if its energy is closest to the one of the n-th state of the corresponding quantum oscillator [28].
We also discuss the effects of different detection photon number on the degree of depolarization of QHG beams, and find that, for small detection quantum number, the polarization fluctuations of quantum light propagation through the turbulent atmosphere can no longer be negligible as the case of classical light propagation in the turbulent atmosphere.
In the Vienna experiment, it is theoretically possible to create entanglement regardless of the strength of the angular momentum or the scale of its quantum number.
