Inversion symmetry erases the distinction between left and right positions in ordinary space. Instead, coherent superpositions of both sites gerade and ungerade states are built, which are energetically non-degenerate. Superimposing these superpositions should give rise to reestablishment of the original position states which should, however, oscillate with a frequency proportional to the energy difference between the original gerade and ungerade states. We show indirect evidence for this behavior in ordinary space analogous to the already observed behavior in flavor space. This behavior was an oscillation between the two strangeness components K and K over time. We observe such an oscillation in ordinary space in an indirect way by probing the asymmetry between so called right and wrong Doppler shifted components of resonant Auger electrons following K-shell photo excitiation of O2. By selecting two types of resonant Auger transition with severely different Auger lifetimes we could make predicitons on the expected asymmetry. The asymmetry values of approximately 0.3 and 0.0 for the two cases predicted by our model could be unexpectedly well verified.
