In atomic nuclei, ordered and chaotic states generally coexist. In this paper the transition from ordered to chaotic states will be discussed in the framework of roto–vibrational and shell models. In particular for 160Gd, in the roto–vibrational model, the Poincarè sections clearly show the transition from order to chaos for different values of rotational frequency. Furthermore, the spectral st...

The CN B 2 -X 2 + molecular emission spectrum is used to measure both the vibrational and rotational temperatures in atmospheric pressure arc jet discharges. The vibrational and rotational temperature effects on the synthetic diatomic molecular spectra were investigated from the v ,v = 0,0 band to the 5,5 band. The temperatures obtained from the synthetic spectra compared with the experimental ...

The photoelectron spectra of FeO and FeO2 2 are obtained at 3.49 eV photon energy. Transitions to the ground state ~D! and three low-lying excited states ~S, S, and D! of FeO are observed. The two low-spin excited states found at 6770 and 8310 cm above the ground state, respectively, have not been observed before. The two S states, characteristic of detachment of a nonbonding electron from the ...
