Under suitable assumptions on the initial state of the particle, we prove a result of local controllability of this processCorrected version with major conceptual changes; 19 pages; LaTex; to be published in International Journal of ControlOptimization and ControlMathematical Physics93C10; 35Q40Point Interaction Controls for the Energy Transfer in 3-D Quantum Systemstext
