The Journal of Chemical Physics, 1949 Formulas are given for an approximation to the energy values of the levels of the asymmetric rotor when the latter are essentially twofold degenerate. The method of arriving at these formulas follows that described recently, in which the energy matrix is examined under conditions where J→∞.

Kinetic theory of light-induced drift of particles with degenerate energy levels
Journal of Physics A: Mathematical and General, 1986 The theory of light-induced drift of particles with degenerate levels is proposed. Kinetic equations which are semiclassical with respect to rotational degrees of freedom and with a phase memory accounting are obtained. The drift velocity dependence on radiation polarisation is predicted. Numerical calculation, which has been made in a strong collision

Mean occupation number for noninteracting paraparticles in degenerate energy levels
American Journal of Physics, 1996 The combinatorial solution of finding the number of ways of distributing n particles into g distinguishable groups such that no group contains fewer than q objects or more than q+a objects is used to obtain the mean occupation number of noninteracting paraparticles in degenerate energy levels.

The physics of the degenerate four-wave mixing process for resonant transitions between two degenerate energy levels is investigated by direct numerical integration of the time-dependent density matrix equations. The Zeeman structure of the upper and lower energy levels is included in a multistate formulation of the density matrix equations.

Physical Review E, 2001 The behavior of quantum states and observables of a quasi-integrable quantum system is studied. Sensitivity of the quantum states and nonperiodicity of the average value of observables at the degenerate points of energy levels are observed. The behavior demonstrates the quantum properties corresponding to the classical resonant tori with rational ...

Effective disappearance of degenerating energy levels
Physical Review A, 1995 Inverse spectral theory provides a theorem on the shifting of a single level, leaving all others unchanged, in a quantum-mechanical system over a finite range in one dimension. We show that the mechanism can be used to remove a pair of states from the spectrum by shifting the energy of one state onto that of a neighboring state. We extend the procedure

Population of Landau energy levels by charged particles of degenerate magnetized Fermi gases
Russian Physics Journal, 1994 The population of the Landau energy levels (from the zero level to the maximum level) is determined as a function of the quantizing magnetic field strength and the charged-particle concentration, for nonrelativistic proton and electron gases and relativistic electron gases.

Orbital angular momentum in triatomic molecules [PDF]
Molecular Physics, 1980 A general method is described for calculating the vibronic energy levels associated with two Born-Oppenheimer states of a triatomic molecule that become degenerate in the linear limit. The method combines Renner's matrix treatment of orbital angular momentum in linear molecules with Hougen, Bunker and Johns' formalism for large amplitude bending ...
