Abstract:
Models are considered in which a particle moves in the field of two moving zero-range potentials (ZRP). Exact wave functions of the three-dimensional problem are constructed for a special choice of the ZRP trajectories. For a one-dimensional model with two uniformly moving ZRPs, stripping and rearrangement are investigated. Oscillations of a new type in the rearrangement probability are considered. In the adiabatic approximation, a general expression is obtained for these oscillations. The results of numerical calculation are compared with the results of the adiabatic approximation.
