A recently proposed model potential to study quantum scattering of a positron from a hydrogen molecule is used to solve the Hamilton equations for scattering trajectories. In the present classical description, the positron can transfer energy to the vibrational mode of the molecule, remaining trapped for a while before escaping to infinity. Such vibrational resonances may correspond to trajectories which are embedded in phase-space regions of chaotic scattering.
一种最近提出的用于研究正电子与氢分子量子散射的模型势被用来求解散射轨迹的哈密顿方程。在目前的经典描述中，正电子可以将能量转移到分子的振动模式，在逃逸到无穷远之前会被困一段时间。这种振动共振可能对应于嵌入混沌散射相空间区域的轨迹。
