Heisenberg Uncertainty Relations and Interaction-Free Experiments

It is shown that a photon resonator can be used for interaction-free control of atom paths within an atom interference experiment. The related "welcher Weg" is discussed and an experiment with an atom interferometer is proposed. When we interrogate the atoms on their way through a double slit setup, the atoms do not arrive at a detection screen so as to form the interference fringes. Therefore by obtaining information on the slit which an atom passed through we can control its motion even when do not pass a single quant of energy to it. Therefore, Heisenberg's uncertainty relations cannot be related to any "kick" exerted to the atom. The obtained results are in agreement with quantum theory.
