The superb control along with the manipulation of ultracold temperature species have permitted access to explore interactions in ensembles of neutral atoms. When these complex systems are excited to Rydberg states, and are very close, consequently induces a blockade effect. The latter has opened the door in order to address many questions and give rise to explore, for example, trimers with multiple correlated systems, ultracold ionic impurities, individual ion-atom collisions and to probe quantum macroscopicity. In this direction, we focus on the direct spatially and temporally resolved S-state wavepacket dynamics of an ion-Rydberg system using our advanced high-resolution ion microscope. By employing a single cold Rb+ ion which facilitates the excitation of a Rydberg atom over thirty micrometers distances, the experimental findings provide evidence to indicate the shape of the wavepacket dynamics in the polarization C4 potential of the ion-Rydberg interaction. These results are compared with the theoretical predictions where it is examined the effect of the adiabatic transition from the S-states with no bound states into the steep section corresponding to non-adiabatic of the high-l states.
