The long-range interactions in ion-atom hybrid systems lead to fascinating phenomena that can be spatially and temporally studied using our high-resolution ion microscope. Our recent studies on a cold ion-Rydberg system with rubidium atoms include observation of novel bound molecular states. Owing to the nature of the long range interactions, the s-wave scattering regime for ion-atom hybrid systems has thus far been elusive. Our proposed initialization of the scattering event via photo-ionization of an ultra-long range Rydberg molecule of lithium atoms combined with the excellent resolution and electric field stability of our ion microscope makes it possible to enter the few partial wave regime.
