Abstract
We consider the problem of energy-mass transfer from scattering to bound states for a one body quantum system subject to the action of a time dependent point interaction in 3-D. Under suitable assumptions on the initial state of the particle, we prove a result of local controllability of this process. Our proof exploits the finite time asymptotic analysis of fractional integral equations and the rank theorem for maps denned on Banach spaces.

†From the physical point of view, the parameter α is linked to the inverse scattering length of H α (Albeverio et al. Citation1988).
