Algebraic description of anharmonic stretching vibrations
Xi-Wen Hou, Shi-Hai Dong, Zhong-Qi Ma
A U(2) algebraic model is presented to describe stretching vibrations of XY (n=2, 3, and 4) systems, where anharmonic interactions between the bond modes are considered. This m…
Fermi resonance-algebraic model for molecular vibrational spectra
Xi-Wen Hou, Shi-Hai Dong, Zhong-Qi Ma
A Fermi resonance-algebraic model is proposed for molecular vibrations, where a U(2) algebra is used for describing the vibrations of each bond, and Fermi resonances between stretc…
Correlations of spin states for icosahedral double group
Shi-hai Dong, Xi-wen Hou, Zhong-qi Ma
The irreducible bases of the group space of the icosahedral double groups {\bf I'} and {\bf I} are calculated explicitly. Applying those bases on the spin states , we…
Irreducible bases and correlations of spin states for double point groups
Shi-Hai Dong, Xi-Wen Hou, Zhong-Qi Ma
In terms of the irreducible bases of the group space of the octahedral double group {\bf O'}, an analytic formula is obtained to combine the spin states into the symm…
Irreducible bases in icosahedral group space
Shi-Hai Dong, Xi-Wen Hou, Zhong-Qi Ma
The irreducible bases in the icosahedral group space are calculated explicitly by reducing the regular representation. The symmetry adapted bases of the system with {\bf I} or {\bf…
Levinson's Theorem for the Klein-Gordon Equation in Two Dimensions
Shi-Hai Dong, Xi-Wen Hou, Zhong-Qi Ma
The two-dimensional Levinson theorem for the Klein-Gordon equation with a cylindrically symmetric potential is established. It is shown that $N_{m}π=π(n_{m}^{+}-n_{m}^{-})=…
