We calculated the power spectra of harmonic generation for the one-electron system in 7 potential models with different quantities of bound states. It indicates that the increase of weakly bound states has little influence on the enhancement of harmonic intensity in the high-order region. Further research on the so-called channel-interference of harmonic generation is obtained, which shows that the channel-interference of harmonic generation exists for all potential models. Therefore, channel-interference maybe a ubiquitous phenomenon for one-electron system driven by bichromatic field, and the increase of bound states can augment the effect of channel-interference. Our calculations can provide some insight on the mechanism of channel-interference and harmonic generation.

The adsorption of O2 over defective La2O3-based OCM catalysts with anionic vacancies , and the reaction of surface oxygen species with CH4 were studied by means of in situ confocal microprobe Raman spectra. The partially reduced oxygen species O2, O , O (O<&<1 ) and even the lattice oxygen ion O2-can be detected on the surface of O2-pretreated La2O3-based catalysts. At lower temperatures (< 573 K) it is peroxide species O- or O- that is more essential for the coupling of methane,while at higher temperature. the superoxide O2 and lattice oxygen species O2-are rather important. It is easier for fluoride-containing La2O3-based catalysts to induce the oxygen species with fewer negative charges and the basicity of the cat- alyst surface is weakened , so that the C2 selectivity for OCM reaction is improved.
