Abstract: The experimental study of collisions is a vast field of physics with a multitude of approaches taken to explore diverse problems related to classical and quantum scattering, resonance phenomena, inelastic processes and few-body systems. As a parallel approach to the beam-target experiments, the quest to explore interactions between particles at very low collision energies has led to technological advances in creating cold, trapped ensembles of atoms, ions and molecules. The low temperatures of the order of a few hundred micro kelvin and the corresponding low kinetic energy of the constituents makes these ensembles ideal for studying interactions and quantum phenomena as opposed to ensembles at higher temperatures where many of the effects are obscured. The techniques of laser cooling and trapping have been extensively developed for both ions and neutral atoms with promise in a variety of applications. An emerging area of research is the cold and ultra-cold chemistry with atoms, ions and molecules as the principal material ingredients [1]. In this context, mixed systems of cold atoms and ions [2, 3, 4, 5, 6, 7] act as a test bench for studying ion assisted cold chemistry [8, 9, 10, 11] and novel many body phenomena [12].
