强磁场中Rydberg NO分子的回归谱研究

利用分子的闭合轨道理论和多通道量子亏损理论,考虑核的转动影响,计算了Rydberg NO分子在外磁场中的回归谱. 研究表明,复杂谱的结构可以用包含分子实散射的闭合轨道理论来解释,不管是同一通道内的弹性散射还是不同通道间的非弹性散射都起着非常重要的作用,尤其是较大标度作用量下,散射作用远大于基本轨道和重复轨道的贡献,很大程度上影响着体系的动力学性质.

Recurrence spectra of Rydberg NO molecules in a strong magnetic field

Considering the influence of core rotation, we calculate the recurrence spectra of Rydberg NO molecules in the strong external magnetic field by using the molecular closed orbit theory and the multichannel quantum defect theory. The results indicate that the complicated recurrence spectra can be explained by the molecular closed orbit theory including the molecular core-scattering. Not only the elastic core-scattering effect arising from the intrachannel scattering, but also the inelastic core-scattering effect arising from the interchannel scattering is vital to the dynamical properties of the Rydberg molecule. Especially on the larger scaled action, the contribution of core-scattering is more crucial than that of the primary closed orbits and their repetition, and affects the dynamical properties of system to a large extent.
