| 英文摘要 | recent molecular-beam experiments have probed the dynamics of the rydberg-atom reaction, h(n)+d-2 -> hd+d(n) at low collision energies. it was discovered that the rotationally resolved product distribution was remarkably similar to a much more limited data set obtained at a single scattering angle for the ion-molecule reaction h++d-2 -> d++hd. the equivalence of these two problems would be consistent with the fermi-independent-collider model (electron acting as a spectator) and would provide an important new avenue for the study of ion-molecule reactions. in this work, we employ a classical trajectory calculation on the ion-molecule reaction to facilitate a more extensive comparison between the two systems. the trajectory simulations tend to confirm the equivalence of the ion+molecule dynamics to that for the rydberg-atom+molecule system. the theory reproduces the close relationship of the two experimental observations made previously. however, some differences between the rydberg-atom experiments and the trajectory simulations are seen when comparisons are made to a broader data set. in particular, the angular distribution of the differential cross section exhibits more asymmetry in the experiment than in the theory. the potential breakdown of the classical model is discussed. the role of the "spectator" rydberg electron is addressed and several crucial issues for future theoretical work are brought out.
