Abstract: We demonstrate a double-trap system well suited to study cold collisionsbetween trapped ions and trapped atoms. Using Yb$^+$ ions confined in a Paultrap and Yb atoms in a magneto-optical trap, we investigate charge-exchangecollisions of several isotopes for collision energies down to 400 neV 5 mK.The measured rate coefficient of $6 \times 10^{-10}$ cm$^{3}$s$^{-1}$, constantover four orders of magnitude in collision energy, is in good agreement withthat derived from a semiclassical Langevin model for an atomic polarizabilityof 143 a.u.
